When finding the right match for specific applications a number of factors have to be considered according to the thickness, weight and size of the cardboard to be used in the application, which varies from one cardboard to another, and whether it will be strong enough to bear the load it is intended to carry after application.
Super glue, a quick drying acrylic monomer cyanoacrylate adhesive, adopts a plastic state when it dries. It provides strong bonds on heavy cardboard as well as on vinyl, some plastics, metal, leather, and ceramics.However, its quick drying and adhesive strength makes it necessary for application to be very quick and accurate, as there is little time available for corrections or repositioning changes after application.
Contact cement adhesives, a neoprene rubber adhesive, is popular for cardboard bonding, and for bonds between the paper-pulp material and other nonporous materials such as plastic, metal, glass, leather and rubber. It is already dry when applied and sets fast, providing a permanent and flexible bond between the two substrates as soon as the solvent has evaporated.
Hot melt adhesives are popular for use on craft projects for bonding cardboard to cardboard, as well as to paper, glass, plastics, and metal, and for attaching extra touches such as cut-outs, buttons, and ribbons. For application the hot melt adhesive is inserted into a heated glue gun in stick form where it melts and is then dispensed through the gun’s heated tip. The applied adhesive grabs quickly, and forms a permanent bond fast.
Tacky glue adhesive, an acrylic-based PVA adhesive often called a “white glue”, dries from white to clear during application and although it is water soluble when wet, it is water resistant once it’s cured. When applied to light or medium weight cardboard, as well as other materials such as plastics, wood, fabric, ceramics, plastics and glass, it produces a flexible, strong, and permanent bond. For ease of application PVA adhesives are packaged in squeezable plastic bottles and dispense adhesive beads through the applicator/cap. Drying time is around half an hour, while full curing takes around 24 hours.
Regular spray adhesives, like tacky glue becomes transparent when it finally does dry, has a longer drying and curing time, and provides a strong and permanent bond between cardboard and plastics, metal, glass, wood, rubber and foam. When heavy load bearing is required for the project, using a heavy-duty spray adhesive may be necessary. Sprays are applied through an aerosol to create an even mist which can cover large areas of cardboard.
Two part epoxies are mixed together before application, triggering a chemical reaction that brings about a permanent bond that’s both durable and strong enough for industrial use as well as for bonding cardboard with a large range of materials such as ceramic, glass, metal and plastics. Epoxy adhesives dry slowly over a period of 24 hours.

Instead of, or working with, the more common underfill approach, the company reports that the edge bonder method is designed to increase the bending and impact strength of the chip carriers (BGA packages or ball grid arrays), and aimed at protecting the printed circuit board and component surfaces from flux residues. It is dispensed using pneumatic valves or through jet dispensing systems.
According to the company, while the viscous thermosetting epoxy resin adhesive bonder is black to conceal the components and block light, to increase the accuracy of in-line optical inspection systems it shows yellow fluorescent yellow when exposed to short wavelength light such as that provided by UV.
The thermosetting adhesive is low in halogens, but has a high thixotropy index and strong viscous flow properties, which allows for precise placement without the chance of subsequent migration according to Panacol. The company reports that two features have been included aimed at meeting environmental bodies’ calls for minimized levels of electronic waste by providing both removability and reworkability. Its removability allows for the adhesive to be removed without damaging components, so that faulty components can be removed and repaired.
Only when the cured adhesive receives thermal exposure over its glass transition temperature of 150°C, does reworkability become possible as, when exposed to such high temperatures, the adhesive softens making it possible to for it to be scraped away manually.

The rapid expansion of the electronics industry due to new technology and the reduction in the size of various electronic devices has led to huge changes in assemblies, different adhesive application requirements, innovations, and adjustments to the adhesive solutions used in electronics assembly. This includes changes in the demand for heat sinks, motor applications, fiber optic cable connections, conformal coating and masking in different electronics applications and assemblies such as hybrid vehicles, digital items, mobile electronic devices, digital cameras, and computers, and the increased involvement in medical applications and telecommunications.
In some assemblies adhesive solutions such as conformal coating don’t stop at the application of one adhesive. Instead, a second solution is needed to protect components with different function from another adhesive in the same application.
Conformal coating, which is based on polymeric film technology is applied to certain sections of printed circuit boards to protect sensitive components from dust, chemicals, moisture, corrosion, and environmental stresses which can impact on those components’ performance in particular areas. However, to prevent possible damage and loss of function in equally sensitive components elsewhere on the board, before the coating is applied a UV curable adhesive mask must be put in place in other parts of the board to protect different components from possible damage caused by the conformal coating
The mask, when applied before the coating, protects areas on the board where components must remain uncoated and electrical continuity is vital for components such as connectors, pins, LED surfaces, and test sites. Being accidentally covered by the conformal coating during its application could destroy their functions. After the conformal coating is safely applied, the masks are carefully peeled off.
Changes have also become necessary in heat sink adhesives which bond increasingly necessary heat sinks to circuit boards and electrical components. With electronic devices becoming smaller, the concentration of the power and correlated heat consumed by them has increased, raising the need for heat sinks to dissipate and transfer the heat in electric vehicles, LED lights, refrigerators, mobile phones and other devices. This has led to an increased demand for adhesives with strong levels of thermal conductivity and strong bonds to link the sinks to components and circuit boards, and transfer the heat to the sink away from the power components.
Other areas that have put extra demands on electronics adhesives include magnet bonding, potting, and encapsulation, and potting fiber optic cable connections.
The brittle magnets used in electric motors, is growing in importance as electric motors take bigger roles in electric vehicles, combustion engines and other transport systems; as well as in computer printers, and household appliances. Adhesives are replacing clips and metal fasteners for these magnets, which are more likely to damage the magnets which are brittle and susceptible to crack under pressure, and add stress to certain parts of the magnet, as well as allowing for vibration, noise, and wear and tear on parts by leaving space between them and the magnet, all problems that adhesives are more likely to solve.
Potting involves adhesives which are used for filling electronic components with a liquid resin (usually epoxies, silicones, urethanes and urethanes) to protect electronic devices from a wide range of environmental threats which can damage or destroy sensitive components in many electronics assemblies. As the electronic devices become smaller, encapsulation, or the removal of the component from the pot once the resin that’s covered it has hardened, for transfer to an assembly becomes more important as it ensures the elements inside the device are strong, durable, and held in place, and so can extend their working life.
Potting is also replacing welding and soldering for fiber optic cable connections. Epoxies and UV-curing systems are used to protect internal components from very high heat, chemicals, and moisture, resist corrosion, and provide optical clarity.

When using stored adhesives, checking the shelf-life and method of storage is important. Provided it is still fluent, the bond is likely to make a strong bond, but when it’s developed a different viscosity, becomes rubbery or stringy, and/or has reached the point where it can’t be returned to its normal fluidity with mild agitation or stirring, it’s not usable. Due to their water content, yellow and white wood adhesives can be stored by freezing, and returned to room temperature unaffected when necessary. Should it appear thicker and grainier at first, these adhesives can usually be brought back to their normal smooth consistency and flow easily after kneading the bottle.
When it comes to woodwork application, factors to be taken into account include both the specific needs of a woodwork project, the materials involved, and the way the adhesive is applied.
In most instances for bonding wood to wood the best application takes the form of thin and consistent lines of adhesive which are then given just enough clamp pressure to cause a very small part of the adhesive to squeeze out.
The amount of water in the wood will also influence the bond and the clamp time. In general, drying happens more quickly when temperatures are high, humidity is low, and the wood is dryer. Drying is slower when temperatures are lower, the wood is wetter, and humidity higher.
When substrates are carefully matched, the wood has a moisture content of between 6 and 8 percent; the temperature is between 70 and 80 degrees; and the humidity levels are between 40 and 60 percent. Clamps should be left on for about an hour to reach full strength. In other situations, such as bonding bent laminations or assemblies, where very high clamping is vital, clamp time can stretch to around 24 hours in order for the adhesive to be at full strength.
Provided the adhesive used for bonding a joint is white and yellow wood adhesive, it can be taken apart once dry by applying heat with a heat gun on the joint line. The adhesive will soften and the joint can be slowly opened with steady and slow pressure.

According to the team, the edible adhesive tape, currently under patent application, is formulated using an organic adhesive and food grade ingredients such as fibrous scaffold as well as other additives commonly used in food.
According to the team, the clear rectangular strips are cut into rectangular strips, each around half an inch by two inches in size, before being attached to waxed paper. To use them, the strips are removed individually from the waxed paper, and wet thoroughly before application. This thorough wetting activates the adhesive before it is applied to the wrap or burrito to keep the folded sections together.

The generic approach to risk management aims to regulate chemicals only on the basis of their inherent harmful properties. The place and method of use of the chemicals are not taken into consideration. Any risk management measures that would arise from a risk assessment are also not considered.
FEICA has stated that, generically, only the classification of the chemical is taken into account, such as carcinogens, mutagens, and reprotoxic (CMR), or other hazard classes currently under discussion, including: endocrine disrupting (ED); persistent, bioaccumulative, toxic (PBT); very persistent and very bioaccumulative (vPvB); persistent, mobile and toxic (PMT); very persistent, very mobile (vPvM); and specific target organ toxicity single exposure (STOT SE) and repeat exposure (STOT RE) respiratory sensitizers.
Professional workers are not consumers and should therefore not be subject to the same restrictions or prohibitions, reports FEICA. In fact, professional users have more characteristics in common with industrial users than with consumers. Professional workers are subject to a comprehensive set of occupational health and safety rules (established in Occupational Safety and Health (OSH) legislation) specifically aimed at protecting them from the risks posed by the chemical substances they handle.

ASME's standard, titled Y14.46 Product Definition for Additive Manufacturing , identifies important features unique to 3D printing and outlines how they should be documented.
The guidance could help engineers from a broad array of industries communicate to manufacturers, product inspectors and others more effectively. Its widespread adoption could clear a persistent roadblock to the application of 3D printing at a larger scale, unlocking the environmental and economic benefits associated with the technology.
“The industry is in a digital transformation right now, moving away from physical 2D drawings, and additive manufacturing is one of the catalysts since it requires digital 3D models,” said Fredric Constantino, an ASME project engineering adviser.“And if you're working on one of those models, this standard will guide you in making it understandable to both 3D printers and other people.”
In addition to producing less waste than subtractive methods, 3D printing also allows for designs of higher complexity, such as those that are not completely solid, but partially hollow, filled with a meshwork that could come in many forms.
The lack of a consensus on how to convey aspects of a product related to 3D printing's distinct capabilities has muddled communication between different organizations and created a barrier to more widespread use of the technology.
ASME responded to this roadblock in 2014, forming a committee of several dozen engineers from industry, academia and the federal government. The group, co-led by Witherell through 2019, sought to produce a uniform approach for defining 3D-printed products.
The committee developed the standard over the course of several years, drawing on input from 3D-printing experts and NIST research. They also incorporated feedback on a draft version of the standard released in 2017.
With the new guidance, the group introduces concepts to address not only the nuances of 3D-printing designs themselves, such as their potentially intricate internal geometry, but the peculiarities of the printing process. Factors, including the orientation of a print and whether temporary structural supports are printed, can influence the strength, durability and other properties of the end product.
Since printers need digital product information to be presented in a particular way, the guidance also includes a section on how to package 3D-model-based data so that it's machine readable.
Designers are meant to reference the new standard along with several previously established standards, which cover basic design considerations that are relevant to a broad array of manufacturing methods.
If adopted by major players in manufacturing, the standard could improve communication for 3D printing, potentially making for a more sustainable and efficient manufacturing industry in the future. However, expanding the standard along the way will be key.

Aside from focusing on achieving the development’s main aim of better performance, the new technology is also pushing for hybrids which match the needs of the existing range of sealant applications, such as filling gaps in buildings to keep the wind, pests, dust, seasonal rain, heat, and chill out of buildings; and which can be applied to them in the same way.
The new technology fusion has led to some changes in the formulation of existing sealants and caulks. The hybrid sealants instead are focused on inclusion of only specific attributes such as silicone’s weathering resistance and polyurethane’s strength with the goal of providing high performance and mechanical endurance.
With these changes, the new hybrid technology is pushing for high solid content which doesn’t shrink, high levels of elongation, and a shorter time period before the surface can be painted. At the same time, the hybrid is being developed to provide UV stability, flexibility, and less odor. They are also designed for less shrinking and cracking which can shorten the sealants’ service life.
The new development is also aiming to make the same hybrids suitable for use in a wider range of substrates including porous surfaces, concrete, wood, metal, stone, plastic, ceramic tiles and gypsum boards; and for providing solutions in a wider range of sectors, like schools, hospitals and offices, for projects such as sealing door thresholds and wooden steps; finishing systems for exterior insulation; panel joints in metal and composite facade; chimneys; as well as bonding metal to masonry, and re-glazing windows.

UV-cured acrylics are also resistant to UV light, chemicals, and oxidation. A key performance attribute of these adhesives is their broad operating temperature range—from 0 to over 240˚F (-18-115˚C)—providing the best performance in both cold and hot climates and lengthening the building season into the colder months. In addition, UV-cured acrylics do not contain any solvents or VOCs, which eliminates all of the associated health, environmental, and long-term durability concerns.
Another installation benefit of UV-cured acrylic adhesives is their workability. Unlike rubberized asphalt and synthetic rubbers, UV-cured acrylic flashing tapes are repositionable for a limited time during the installation process. If the tape’s initial application needs to be adjusted, the installer can simply peel it up and reapply it to ensure best performance. This is simply not possible with tapes incorporating traditional rubberized asphalt and synthetic rubber adhesives; their removal can be difficult, and the used tape must be disposed of.
Moreover, the properties of UV-cured acrylics can often be customized to suit specific OEM manufacturer needs, even down to the product level for particular flashing tape application requirements. For example, the thickness can be adjusted to suit rough substrates such as OSB. With specifically formulated properties, the adhesive is able to fully flow into the cracks of rough substrates and maintain a strong bond.

Time is an important factor when it comes to ease of application, how long applications take, and the life-span of the bond, but time demands and controls vary according to the types of adhesives used.
With regard to the application process, the pot life, or length of time during which two-part adhesives can be applied once they have been mixed together, is vital. Equally important when using single component adhesives is the open time, or how long these single component adhesives can be exposed to air between application and assembly. Other time considerations include clamp time, or how long bonded wood should be clamped after application to prevent excess stress; and the curing time required for the adhesive bond or joint to reach full strength. Shelf life, or the time period during which unused adhesives remain usable, is also extremely important.
Outside influences such as the location where the assembly is carried out, the environmental weather; and the adhesive’s temperature and water resistance levels. High creep levels, or tendency to not snap back after slips or stretches under long-term loads, are most commonly found in white glue and PVA adhesives. High creep can affect the adhesive’s performance and result in adhesive lines being left behind; misshapen laminations; and even joint failure.
The most popular woodwork adhesives each have advantages and disadvantages. Epoxy two-part adhesives (one of which is a hardener to mix with the resin in the other) have a pot life of 4 to 50 minutes, allow for 5-30 minutes exposure to the air between application and assembly, and require curing periods which range from 15 minutes to 15 hours. They also have excellent temperature resistance and remain usable for two or three years. Recommended applications are outdoor furniture, laminations, marine applications, and structural gap-filling. However, gloves, glasses and respirators are advised for both sanding and mixing.
Polyurethane has a 15 to 30 minute window for exposure to air between application and assembly, requires clamping hours of 1 to 4 hours, and is a good choice for wet woods, and bonding wood to a non-wooden substrate. It has excellent temperature resistance and a two to three year shelf life. However, it requires moisture, and complicates the clean-up afterwards because of the foam it produces while curing.
Urea Formaldehyde, a two-part adhesive available as either liquid or powder, is considered the right adhesive for use in veneering and for bent laminations. It has a pot life of two to four hours, 5-30 minutes open time, and 5-15 hours of curing; remains stable in temperatures as high as 180 degrees F, and has a shelf life of one year. However it is not suitable for submersion on a constant basis. It also requires gloves, glasses and respirators during application.
Considered the best adhesive for fast repairs, Cyanoacrylate offers only 1 minute of open time, and the same for curing. It has low temperature resistance and a one year shelf-life. A debonder may be necessary for clearing spills during application.

Overall housing starts fell 14.4% to a seasonally adjusted annual rate of 1.55 million units in May from an upwardly revised reading the previous month, according to a report from the U.S. Department of Housing and Urban Development and the U.S. Census Bureau.
The May reading of 1.55 million starts is the number of housing units builders would begin if development kept this pace for the next 12 months. Within this overall number, single-family starts decreased 9.2% to a 1.05 million seasonally adjusted annual rate. The multifamily sector, which includes apartment buildings and condos, decreased 23.7% to an annualized 498,000 pace.
“Single-family home building is slowing as the impacts of higher interest rates reduce housing affordability,” said Jerry Konter, chairman of the National Association of Home Builders (NAHB) and a home builder and developer from Savannah, Ga. “Moreover, construction costs continue to rise, with residential construction materials up 19% from a year ago. As the market weakens due to cyclical factors, the long-term housing deficit will persist and continue to frustrate prospective renters and home buyers.”
“In further signs that the housing market is weakening, single-family permits are down 2.5% on a year-to-date basis and home builder confidence has declined for the last six months,” said NAHB Chief Economist Robert Dietz. “Due to the acceleration in construction activity in recent quarters, housing completions are rising. Single-family completions were up 8.5% in May 2022 compared to May 2021 as inventories rise.”
On a regional and year-to-date basis, combined single-family and multifamily starts are 2.1% higher in the Northeast, 1.2% higher in the Midwest, 12.9% higher in the South and 4.3% higher in the West.

These include filling gaps and cracks easily in both old and new buildings; strengthening the wall structure; ensuring that the insulation lasts; reducing unnecessary noise; lessening the chance of pollen and allergens, insects, rodents and bugs from entering the house; and lowering the risk of mold and mildew build-up.
When dealing with specific insulation projects, a choice needs to made between the two types of adhesive spray foam (open cell or closed cell). Both are suitable for application in most insulation problems. However, because of their formulations, one is sometimes more effective than the other in specific applications.
The open-cell spray foam is spongier because its cells are open to air, which makes it more effective in reducing unnecessary outside noise, while the solid and rigid formulation of the closed cell adhesive spray foam is more effective in strengthening structures and providing strong barriers to stop large amounts of air and water from getting through the walls. It also blocks the impact of strong winds, heavy snow as well as heat and cold, and lessens the chance of pollen, allergens, insects and rodents getting into the house by filling the cracks and gaps in the walls and roof.
Choice of which to use is often based on both the age of the house, and whether it is being built or renovated, as older homes are more likely to have bigger cracks and gaps than the other.

Purdue researchers led by Jonathan Wilker, a professor in Purdue’s College of Science and College of Engineering, created a patent-pending adhesive based on zein, a protein in corn. The adhesive is degradable, nontoxic, and tunable, which means it can be adjusted for strength, flexibility, and performance in extreme temperature, moisture, and high-vibration conditions.
Rachel Freedman and Dan Rosen are co-founders of gluECO Adhesives (Freedman is primary owner and Rosen is CEO). They realized the need for environmentally friendly adhesives when they prepared to sell their house.
“We were dismayed we could not recycle the hundreds of hardcover books we owned,” Rosen said. “We found out it was due to the adhesive. A few years ago, I came across an article by Jon and had even spoken with him. Rachel and I re-established a relationship with him to learn about his zein-based adhesive.”
The R&D team at gluECO will build on Wilker’s research. Zein reportedly imparts additional properties beyond adhesion, including being a highly effective oxygen and water barrier, as well as the ability to be molded, extruded, or spun into filaments. The company also has entered into an exclusive manufacturing agreement with FloZein Products, the only zein manufacturer in North America. The initial market will be industries and applications that require specialized adhesives.
“Our adhesives will be 100% bio-based and food safe,” Rosen said. “This makes them ideal for any food or pharmaceutical product that may have direct contact with adhesives and packaging. In addition, we are exploring applications where the adhesive acts as a specialty polymer to create composite materials. Our R&D team will also develop custom formulations based on inquiries.”
Rosen said gluECO plans to exercise its option and negotiate a license to the zein-based adhesive from the Purdue Research Foundation Office of Technology Commercialization (OTC). The office manages Purdue University intellectual property, including vetting, applying for protection, marketing, and licensing.
“Jon Wilker, my colleagues and I have great respect for Rachel, Dan and their work to address a serious environmental and health problem,” said Joe Kasper, assistant director of business development at OTC. “It is exciting to think about the lives that will be improved by using gluECO’s adhesives in place of traditional petroleum-based adhesives.”

To make sure the force, tensile, and shear levels are compatible with the material used and meet its process specifications, tests have been developed to determine both the strength of the adhesive being used and how well the material copes with the force of the adhesive. This is done by measuring the adhesive strength as well as the material’s support levels and reaction strength by tracking and measuring the displacement which occurs when the materials are stretched. The results are then recorded in a graph which logs the curves of both the adhesive force and the displacement of the materials.
The same information is then transferred to a second graph to determine the tensile stress of the adhesive against the strain it places on the materials, and so indicate the specific levels of stress the material can and can’t withstand.
This testing is generally best done to match specific applications when more considerations have to be taken into account such as the nature of the bonding, the mechanical forces that are active, and the environment in which the product is to be made and how these factors affect the test results as well as the application.

Proper sealant in crystalline silicon (c-Si) panels has been shown to extend lifetime power output. EVA encapsulants can be problematic with the potential to generate acid that can sap the panel of its power due to the corrosiveness of the acid when exposed to moisture over time. New technologies like perovskite solar cells (PSC) and heterojunction (HTJ) cells show promise of higher module efficiency but have shown greater moisture sensitivity and therefore also require greater moisture protection.
Applying the proper sealant to new solar modules has been shown to help delay loss of power over a module’s lifetime by significantly delaying any degradation mechanisms activated by moisture; extend useful life without any other changes to existing design; maximize cell area increasing aperture efficiency; and maintain excellent environmental performance in high-heat conditions.

The most important properties required are fire retardance and flame resistance, both of which play a part in slowing the spread of fires in different ways.
In the event of a fire, retardants are able to help put out the flames, or at least slow them from spreading, which make them suitable for many industries such as electronics, construction and transportation such as public transport or aircraft. Flame resistance, on the other hand, can not necessarily stop the fire from happening, but it has strong resistance to the flames and to high temperatures. This resistance, usually found in adhesive cements and inorganic sealants, makes the adhesive non-burning, and so reduces the chance of fire starting during application. At the same time, the resistance helps stop any flames that do occur from getting out of control by trapping any burning bits, and so lessening the likelihood of it spreading.
Other crucial properties are also required when choosing the correct adhesive, most of which are developed specifically for individual application in the growing range of industries such as aerospace, construction, electronics and public transport, in order to comply with the needs and regulations regarding individual industries.
Regulation approval is largely based on fire retardance levels in the application such as bonded joints, as well as in materials used in the assembly. Testing is drawn out and complicated when composites are part of the assembly. Each layer has to be tested to confirm that the adhesive used is flame-retardant or non-burning.
Regulations also call for other adhesive properties such as not giving off large amounts of smoke during an event, and particularly not when the smoke is toxic; ensuring that adhesive material, when decomposed, does not contain any toxic by-products; and the temperature resistance is able to maintain structural integrity when the temperature is high.

The growing rate at which the switch over is being made has led to a projection that corrosion protection adhesive tapes will see a rise in compound annual growth rate of 4.4% from 1.2billion US dollars to 1.8 US dollars in the next decade.
Easily applied, protection adhesive tapes, have high levels of strength; are resistant to temperature, water, and shear; and include flame retardance. Available either in rolls or as die-cut sheets, the tapes take the form of a thermoplastic plastic film (usually PVC), with one side of the film backed with a high strength adhesive to protect surface areas from corrosion caused by UV, water, temperature threats and for electro insulation.
They are now also take a major role in protecting structures manufactured using two separate metals from coming in direct contact with one another to avoid electrochemical galvanic corrosion which can develop when the two metals have different electrode potentials and come into direct contact with one another, and an electrolyte is present.
To avoid this, the tape covers one metal to separate the two metals in order to prevent direct contact which, under the influence of the electrolyte, can lead to one of the metals taking the role of a positive cathode, and the other that of a negative anode. This can lead to metallic ions moving from the negative anode to the positive cathode and over a period of time weaken the structure and shorten its life span due to galvanic corrosion.

According to US Conagen, the bio-based adhesive is not reliant on a petroleum base, and is easy to apply and quick to cure. It is also reversible, debondable, and designed to become a flowable material after heating when necessary. These bio-based hot-melt adhesive benefits, according to the company, allow for any last-minute changes in the bond, and decrease the waste of materials and time caused by non-debondable adhesives which have to be discarded when changes are necessary. The company reports that this simplifies the recovery of parts and materials for recycling from products which have reached the end of their life-span.
The company reports that the adhesives have been developed for use on a wide range of materials such as glass, metal, and plastics, and aimed at various industries such as marine and military, aerospace, consumer electronics and appliances, and automotive assemblies.

In choosing the right sealant tape to use on a specific RV, compatibility between the material used on that RV’s roof and the sealant tape is essential for a good and lasting outcome. When it comes to modern RV roofs, which largely are made of rubber, there is compatibility with most sealant tapes. However, for older models, with metal or fiberglass roofs, finding a sealant that’s compatible could be more difficult.
For a long-lasting solution, other factors that should be considered include UV-resistance in addition to water-resistance so as to ensure that these two threats, when combined, do not wear down the insulation of the RV leaving the interior colder, and damaging some of the RV structural parts.
When maintenance checks have been overlooked, and the damage has already been done and the RV has leaks or a hole in the roof, heavy duty sealant tapes teamed with a RV Cover might be necessary to avoid further impact of both sun and water.
Sealant tapes are mostly available in long rolls of 4 inch wide tape, but where these are considered too narrow for the task in hand, they can be teamed with liquid sealants in order to broaden coverage. Application is best done using a roller.

Like the other materials tested in the company’s series of studies so far, the interaction and performance achievement of adhesive bonds with cellular rubber were carried out at the ISO 17025-certified Avery Dennison Performance Tapes Painesville Innovation Centre. There tapes are subjected to tight environmental control which allows for testing the adhesive performance tapes’ performance in both extreme and real-world conditions.
Challenges provided by rubber bonding include the risk of impact on the bond caused by the material’s own base polymer, cell type, and thickness; or by some factors provided by the adhesive tape itself. These include lamination speed, temperature, adhesive mass, compression and pressure.
To remove the possible threat to the bonding performance posed by the adhesive tapes tested, the two adhesive tapes chosen for the two test sets of adhesive tape performance on Rogers Griswold cellular rubber products were backed with a 2mil PET film and cut down to one inch in width before being laminated to the rubber material. Both sets used 30% compression at 20fpm, but bonding was done under different temperatures. One set was carried out at room temperature, while the other at 220°F, and a 72hour post lamination recovery period was allowed.

Instead the dots (or windscreen frits) made of enamelled ceramics are there to increase the performance and lifespan of the bond between the vehicle and the windshield glass by providing a rougher surface for the application which leads to stronger adherence and longer lifespan.
To ensure the effectiveness of the bond, the frits are placed so close together on the edges of the windshield glass during manufacture that they take the form of a black belt, and it’s this “belt” which roughens the glass for better bonding, and also blocks the sun’s ultraviolet rays from damaging the adhesive.
However, to regulate the temperature, which tends to rise in the black belt area fast, which can create optical distortion, the individual dots are spread out on the glass in arrays of gradually smaller and more separate dots from the edge of the belt inwards on the windshield, so as to assist with equal heat distribution over the entire windshield.
In other areas, such as a gathering of dots around the rear view mirror, the aim is to offer a shield from the sun’s rays for those in the vehicle where no sun-visors are installed.

Decades later, I can easily relate to that bold statement, as tape indeed has turned out be a large part of my life as well. With the World Adhesive and Sealant Conference upon us, what does the world of tape look like today?
Growth Opportunities
One consistent hallmark of the global tape industry has been that of steady growth. Despite the challenges of COVID, supply chain issues, and a host of other difficulties, the pressure-sensitive tape market will continue to expand, with global growth rates predicted to be over 6% through 2030.
This increase is driven in part by pressure-sensitive tape’s high degree of functionality, which in turn often results in savings of time and money, quality improvements via enhanced performance, and improved aesthetics. In multiple examples across several markets, process improvements such as reduced preparation time and decreased downtime add to the overall value generated by pressure-sensitive tape use. In short, tape often presents the optimum tailor-made solution for many customers.
Because of these advantages, PSAs are well-positioned to tap into multiple emerging trends. With labor shortages affecting multiple markets, tape solutions offer ease of use and often enable a high degree of automation implementation.
In terms of environmental awareness, the tape market is a leader when it comes to implementing solvent-free adhesive solutions such as hot-melt and other solvent-free options. Building on the legacy of providing repulpable (water-soluble) adhesives to the traditional paper industry, tape manufacturers are increasingly offering water-based adhesives for more advanced applications in multiple end-use markets.
Aligning with the sustainability mantra of reduce, reuse, and recycle, look for the tape industry to continue to innovate. One emerging technology field is literally going back to nature to develop bio-inspired adhesives. Some of these products are loosely based on van der Waal’s forces, utilized in the natural world by the gecko, among others. Such adhesives not only allow for ease of initial application but subsequent repositioning and reuse, which has the impact of not only providing a secure bond but one that is repeatable and therefore reduces the need for additional material.
The boom in e-commerce certainly has driven an increase in demand in the packaging and adjoining industries, where tape often plays a key role both in process and end use. Pressure-sensitive tape often helps achieve lightweighting targets by replacing heavier mechanical solutions. Finally, did you know that it is actually possible to “tape” an entire residential or commercial building envelope utilizing pressure-sensitive air barrier technology?
Industry Challenges
The industry does indeed face several of the same threats confronting multiple markets today, among them rising input costs, supply chain volatility, and availability of labor. All of these factors will drive tape manufacturers to initiate process improvements where possible, rethink and potentially shorten supply chains, and partner even more closely with suppliers.
On the regulatory front, the tape industry in North America is at the forefront of looking to expedite the reduction of hazardous air pollutants (HAPs), driven by Title III of the Clean Air Act Amendment. With the U.S. Environmental Protection Agency (EPA) scheduled to review current pollutant floor levels, all web coating operations in the U.S. (including tape manufacturing) will have Maximum Achievable Control Technology (MACT) emissions testing required by 2023.
At the state level, California Proposition 65 requires close attention for companies that wish to manufacture or sell product in the state. Internationally, European REACH compliance requires consistent monitoring, with a most recent call there for restrictions on the use of mid-chain chlorinated compounds (MCCPs). All key tape manufacturing regions of the world (North America, Europe, and Asia) offer unified pressure-sensitive tape industry associations that help members navigate the regulatory maze in their respective areas.
Wide-Ranging Solutions
While tape may not be your life, perhaps you could consider how it could become a potential solution to a problem you may be facing or a means to improve a process you are responsible for. Experts throughout the PSA value chain would be glad to speak with you and explore potential opportunities.

According to MasterBond, the shims are designed to provide high compressive adhesive strength to address problems like gaps forming between the different materials used in composite assembly; and to provide high performance even when faced with various environmental conditions which can arise during application. These include exposure to water ingress or fuel, or are subjected to high or low temperatures.
The company reports that liquid epoxy shims offer a number of benefits such as withstanding CTE mismatches between the different substrates used in composite assembly, and resistance to forces in the bonded surfaces plane. The shims have high lap shear strength, and low slump which allows its shape to be consistently held. They are also, according to the company, resistant to abrasion, micro-cracking under exposure to high temperatures, as well as to impact, shock, and vibration.
The toughened thixotropic compounds used in the shims allow for vertical application and a long lifespan. Curing of two component bonding can be carried out at room temperature or moderate heat, and application can be simplified by using the custom packaged dual component cartridges for both more convenient application and for ensuring that the mix efficiency remains consistent. The shims can be stored in ambient temperature.

The competitive significance of the consolidation experienced in 2021 is unprecedented. Global transaction multiples are at record levels and expected to remain strong. Buyers have access to large amounts of capital and are prepared to invest in M&A opportunities.
Primary Strategies Driving Consolidation
Two distinct strategies are at play in adhesives and sealants segment M&A—one being employed by large, global consolidators and the other by domestic, private equity-backed consolidators. Global consolidators are large cross-border market participants that are publicly funded and often seeking supply chain vertical integration. Adhesives and sealants companies with significant resources have fared better than their smaller private competitors. Companies such as Arkema, Sika, and H.B. Fuller Co. will continue to aggressively pursue growth opportunities through strategic acquisitions. Only a few mid-size private companies have survived the past 20 years of consolidation.
Private equity-funded consolidators are relatively smaller platforms that rely on local and domestic markets. As private equity continues to get involved, competition from growing private equity platforms will continue to put great pressure on small and mid-size companies that do not have an effective strategic plan in place. These are adhesives and sealants companies that gain scale through add-ons without a pronounced taste for vertical integration. Examples of such serial acquirers include Applied Adhesives, Meridian Adhesives Group, Royal Adhesives & Sealants (H.B. Fuller), and Quest Specialty Chemicals.
Small businesses dominate the U.S. adhesives and sealants segment. The adhesives and sealants processors analyzed by Blaige comprise hundreds of companies. As shown in Figure 2, the adhesives and sealants segment is made up of primarily small to mid-sized companies; 84% of processors have annual sales of less than $100 million, with 73% under $50 million.
Aggressive consolidation among large-cap companies is increasing pressure on the smaller participants, making it hard to survive and thrive. Of the top 50 North American adhesives and sealants processors in 2001, 64% have been eliminated, sold, or experienced an ownership transition over the last 20 years, as opposed to 38% a decade earlier (see Figure 3). The remaining 36% of survivors are either private equity-owned or global consolidators with sales of more than $500 million. These companies possess the resources to...

]]>Degradation due to solar radiation (or sunlight), heat, and humidity are often a concern when organic and polymeric materials such as adhesives are intended for outdoor use. The photochemical effect of sunlight on a polymeric or organic material depends on the absorption properties and the spectral sensitivity of the material. The wavelengths that typically have the most critical effect range from 295-400 nm (ultraviolet radiation, UV). Solar radiation can cause the formation of radicals that can lead to matrix and additive degradation.
Temperature is also an important factor in weathering. Surface temperatures under irradiation depend on the material’s absorption and insulation properties. Typical maximum temperatures of irradiated surfaces are represented by black painted metal plates. Black standard temperature (BST) is determined with sensors that have backside insulation, while black panel temperature (BPT) sensors do not have backside insulation.
High temperatures can cause thermal degradation while also accelerating other degradation and diffusion processes. Temperature cycles can also lead to mechanical stress by expansion and contraction, which might impact the adhesive strength.
Finally, moisture in the form of relative humidity or as liquid water (rain or dew) has an influence on material performance. Moisture can cause hydrolysis reactions in some instances, but moisture cycles can also result in mechanical stress to a material that might also impact the adhesive strength.
These stresses together can lead to cracking and delamination effects, even though the adhesive is not directly exposed to the environment. Table 1 gives an overview of the most important weather parameters for...

According to the university research team, the design of the new polymer adhesive, with its adhesive strength and performance could provide a good platform for use in the assemblies of new and different materials, therapeutics, and biological environments, and possibly be used for bonding to particular body tissues.
The researchers credit their positive results to their approach which differed from that taken by other scientists in the past. Instead of trying to replicate the mussels’ natural protein-based adhesive and its qualities and performance shown in its ability to ensure survival in a harsh habitat subjected to heavy waves, they focused on formulating a synthetic adhesive polymer based on the creatures’ assembly.
Instead of centering on replicating the mussels’ structure and some or all of the molluscs’ eight proteins as earlier studies have, they switched to studying the unusually careful precision with which the amino acid chains (peptides) in them are positioned. The researchers report that the team discovered that by shifting molecules it was possible to assemble amino acid components with similar precision to that applied by the molluscs but without replicating the proteins’ structure exactly. According to the researchers the addition of a fundamental foundation and one of the mussel enzymes to the synthetic polymer, had contributed to the performance and strength of the synthetic polymer.

Compostable and biodegradable adhesives, while classified separately, bring about the same end result by breaking down materials completely with micro-organisms like bacteria and enzymes, but their way of achieving this end differs in how they decay, and the length of time they take to deteriorate completely, which can affect their performance in specific applications.
Biodegradable adhesives in general ( which includes compostables) have molecular structures similar to those of natural polymers, and are broken down easily by micro-organisms and the enzymes they produce in much the same way as the natural ones, and materials can be broken down easily into carbon dioxide, water and biomass.
What makes a difference is that biodegradables degrade naturally and very slowly, while compostables, before they can be classified as such, must have a specific break-down process which can complete biodegradation in a specific time period far shorter than that needed for natural degradation. This allows for compostable adhesives which, depending on their formulation, breaking down into re-usable and harmless components far more quickly, and they can do so in both domestic and industrial conditions.
Currently biodegradable adhesives are mostly offered as liquid, hot melt or heat seal solutions, particularly when it comes to plastic food packaging and paper and biofilm applications. Pressure-sensitive (PSA) adhesives integrated with compostability, are being used for tape and label application.

The collective goal was to increase the volume of guar harvested annually through educational programs and scientific solutions for sustainable farming while respecting the sourcing relationships and local cultures of small village farmers in the Sriganganagar district of Rajasthan, India. These relationships are reportedly critical to the company, which uses guar to formulate specialty ingredients for coatings, personal care, and life sciences applications.
The pilot program included 250 farms from 10 villages. Using modern technologies, farmers were taught sustainable agronomic practices and water conservation. The program’s successful results include helping farmers lower their production cost while increasing their crop yield approximately 30%. In addition, the program has helped increase farmers’ income, thus expanding the local economy in the small villages.
At the same time, Ashland reports that its commitment to gender equality led to specific training focused on the local female population to empower them, improve their technical knowledge and skills, and help elevate their standard of living. Based on the success of the pilot, Ashland is moving forward with plans to increase the number of farms to 5,000 by 2025.
In addition to aiding the farmers with guar production, Ashland’s Responsible Solvers mindset led the team to provide training and other technical guidance for mustard and wheat crops during the guar off-season. This training also reportedly improved the yield of these crops, making a holistic impact on the farmers’ annual income.
“Our commitment to profitable, sustainable growth includes a strong innovation culture, sustainability-aligned technology portfolio, goals for the environment, social initiatives, and continued strong ethics, compliance, transparency and governance,” said Guillermo Novo, chair and CEO, Ashland. “In this instance, providing STEM skills and education both on and off the field to small farmers is having a very real, positive impact in their lives and in their small village communities. In addition to maximizing shareholder value, as we innovate, Ashland will continue to act in a manner that contributes to the welfare of society and the environment.”

These elements are reported to be currently worsening the infrastructure of 20% (or one in every five miles) of major roads and highways, particularly in those states which are particularly subject to snow and cold weather.
While using topical sealants on bridges and concrete structures in order to protect them from the elements outside has been used for some time, according to the researchers adding a sealant which includes these moisture and salt resistant nanoparticles to the concrete microstructure itself could be far more successful at prolonging the strength of the roads’ internal strength.
They report increasing the strength of the concrete’s microstructure, which the researchers identify as being a very porous and non-homogenous composite, by making it’s sponge-like consistency denser, and so reducing the likelihood of moisture and salt being able to penetrate it.
This, in turn, they report, could lengthen the lifespan of US roads by cutting back on the amount of damage currently caused within them by melting snow and rain, as well as by salt that’s in the process of de-icing, which can result in physical and chemical damage.
According to the researchers, tests showed that the new sealant containing the nanoparticles, and made from water, was 75% more able to repel water and 44% better in reducing damage caused by the salt than those that did not.

While the typical surgical mask remains part of the new type of the mask, the change in effectiveness is the result of a new rubbery silicone adhesive harness which holds standard surgical masks in a way that they fit better, and stay in place longer, without droplets entering the mask.
As part of the study conducted at Rice University, the nose and eye areas were identified as being the areas where air was the most likely to leak in and out of standard masks that were not snugly fitted. This was confirmed by airflow tests carried out using an infrared camera, which tracked the amounts of droplets and air movement in standard surgical masks worn by volunteers.
The harnesses, together with the surgical masks, were passed by a filtering face piece respirator evaluation in which the harness and mask combination was found to improve effectiveness by 15 times compared with surgical masks on their own in lessening the number of droplets.
To ensure this improvement in mask protection from droplets while avoiding the risk of it interfering with a surgeon’s eyesight if too big, the researchers changed the shape of standard surgical masks, but extended the length of the silicone adhesive harness to ensure a tighter fit over the nose that would last longer. The masks remain one-use-only, but the harnesses can be removed and re-used after sanitizing.

This breakthrough has resulted in an adhesive capable of holding 300 lbs (136kg) in weight, and of functioning and enduring temperatures of up to 400°F (200°C), done by upcycling the materials used in the commonly used plastic. The researchers report that this could lift the household plastic to new levels of adhesion, possibly including meeting the needs of the construction industry, automotive assembly, and aerospace.
According to the researchers, the crosslinking resulted in an adhesive which combines the characteristics of both strong adhesives, which provide strong bonding but can easily become brittle, and ductile adhesives which don’t have the same bonding strength, but are more flexible and better able to withstand stress.
The dynamic crosslinking which the scientists report increases the strength of the SEBS plastic (comprised of elastomers) by combining the plastic’s materials, which fall in the ductile class, and therefore have lower bonding abilities, but high flexibility and strong resistance to stress, with silica nanoparticles often used to strengthen plastic. This was accomplished by using boronic esters.

According to Henkel, LPM hot melts completely replace thermoplastic housings and allow manufacturers to produce complex and intricate assemblies by customizing part geometry, surface texture, color, and opacity. These materials form an adhesive bond with the entire component being encapsulated, becoming part of the component’s three-dimensional form and creating a water-tight, chemically resistant seal. The cost-effective LPM process involves three steps: placing the bare component into a custom mold set, heating the polyamide material and injecting it at low pressure into the mold, and allowing the material to cool rapidly for 10-50 seconds before removing the newly encased and bonded component for immediate use.
Formulated to allow greater design freedom than traditional medical encapsulants, Loctite PA 6732, Loctite PA 6682, and Loctite PA 6951 are single-component, solvent-free polyamides that are solid at room temperature. Derived from natural fatty acid feedstocks obtained from renewable resources such as soy, rapeseed, and sunflowers, they are green and sustainable. No harmful fumes are released during the molding process, and all products are RoHS and REACH compliant.
Loctite PA 6732 is an amber material that performs well in temperatures from -40 to 140°C. Clear Loctite PA 6682 is designed for use in temperatures between -25 and 105°C. Loctite PA 6951 is a colorless material that performs well in temperatures from -40 to 100°C.

In producing these bandages biodegradable materials are used such as coconut oil and bamboo fiber, which, like other bandages, are adhered to the skin with a hypoallergenic Pressure Sensitive Adhesive usually developed by combining natural minerals and nano technology. These adhesives adhere gently and lessen the chance of reactions in those with allergies or are sensitivity to anything being applied to the skin.
Biodegradable adhesives refer to glues that break down naturally, eventually. Compostable adhesives are also biodegradable, but they only deserve the title if they comply to a specific break-down process, and do such within a restricted period of time. Compostable adhesives may break down in domestic or industrial conditions, depending on the adhesive formulation. They take much less time to break down into useful or harmless components than biodegradable materials generally do.
The biodegradability of the materials involved in these organic bandages allows it to decompose naturally when disposed with after use, so lowering the levels of disposal impact in the landfill.

Sealing the gaps and cracks around windows and doors using a caulk sealant is best done with a caulk gun for ease of application, ensuring the application is accurate, and seeing to it that the sealant is properly bonded and therefore able to perform at its best for a longer period.
The right caulk sealant for use in the gun on doors and windows should be a sealant that is totally comprised of silicone. It should also be permanently waterproof, flexible, and shrink and crack proof for a long term. Paintable silicone caulk adhesives that can be painted are also available should there be a need to paint the area.
Preparing for sealant application using a caulk gun calls for prepping. This involves removing dirt and residue from the surface with a damp cloth, and scraping away any old caulk that has previously been inserted in the gap. The silicone adhesive is inserted into the gun once the tip of its tube is trimmed at a 45% angle and the seal on the cartridge is pierced, allowing the caulk to flow.
Application to the surface is done by squeezing same-sized beads evenly to the prepared areas, one at a time. A consistent speed is required, as is releasing the trigger before taking the gun away to caulk a different section. It is then smoothed out with the tip of a finger.
An alternative approach to cutting down on unwanted incoming cold air or outgoing warm air and the energy loss it causes, particularly on gaps and cracks surrounding windows or doors, is using self-adhesive pressure sensitive adhesive tapes, some of which are specially produced for the purpose of cutting back on drafts.
Application simply involves cutting the tapes to the precise length needed, pushing it into the gap, and pressing the adhesive side of the tape against the framework.

Double-chamber cartridges have the advantage of making it possible to work with media like adhesives, pastes, or silicones with two components of different viscosities. Many adhesive processes depend on these components being mixed in a precise ratio. The two applicator cylinders are moved independently of each other in this process, and the correct adhesive mixture is applied to the components to be glued, according to the company.
Minute quantities need to be applied precisely and reproducibly to circuit boards, for example, or gaps need to be precisely filled on different electronic components, often using highly abrasive pastes. These application conditions make correct control and indication of the delivery pressure crucial. According to the company, the appeal of this new development is that the precision application of the adhesive leaves no rims of adhesive on displays or micro-cameras, as well as no adhesive oozing from the corners and edges on glued components in everyday consumer goods.

To meet these requirements the focus has been put on high-tech non-rigid and flexible adhesives of the kind used for bonding component parts, instead of the rigid ones used for rigid assemblies of durable machinery and motors. Many of the non-rigid adhesives, which usually fall within the hot melt, dispersion, or powdered adhesive categories, are being chosen for laminating or bonding several, often different, layers of materials and membranes permanently in such a way that the end result appears to be a single material while allowing the skin to breathe.
Complicating the adhesive requirements for clothing and footwear ranging from lingerie and outdoor clothing to surgical gowns and protective clothing (including for sports) is the challenge posed by the fluid and flexible materials used in these products, and the way they are applied. Requirements involve solutions which provide strong and permanent bonds between multiple materials while allowing the skin to breathe. Applications include lamination in multi-layer product assembly, providing air and liquid filters, and flocking.
Certain other factors have to be included when considering the adhesives used. With outdoor and sports clothing, adhesives and lamination must be able to withstand dirt, UV exposure, and the stresses placed on both materials and adhesives by washing machines. Protective clothing must be able to resist chemicals and fires; and surgical gowns need to be able to resist both hydrolysis and sterilization.

To meet the varied requirements of the different products in these sectors, a range of non-rigid and flexible adhesives, most of which fall within the hot melt, dispersion or powdered adhesive categories, have been designed for specific applications. These range from lingerie and outdoor clothing to surgical gowns and protective clothing.
The amount and types of flexible material used for different clothing may differ considerably, however many of them follow similar paths when it comes to adhesives, with most using non-rigid adhesives to permanently laminate together layers of very different materials into what appears to wearers to be a single material.
Included in the many layers of material bonded by the non-rigid adhesives are usually membranes which ensure that while the lingerie, outdoor, surgical gowns, or protective clothing keeps the wearer dry, warm, and comfortable, the skin is still able to breathe.
However, in sectors other than lingerie, certain other factors have to be included when considering the adhesives used. The outdoor clothing adhesives and lamination must be able to withstand dirt, UV exposure, and the stresses placed on materials and adhesives by washing machines. Protective clothing must resist chemicals and fires; and surgical gowns need to be able to resist both hydrolysis and sterilization.

Adhesive diagnostic medical tapes differing in size and complexity are used in diagnostic devices in accordance with the device, the application it requires, and the nature of the diagnosis. This involves testing, detecting, screening, and/or checking for the presence (or levels) of pregnancy; blood; glucose levels; drugs; microbials; pathogens; and genetic analysis.
Unlike those adhered to the skin, these adhesives are not faced with regulations or standardizing testing as they aren’t in contact with the patient or their skin, and therefore pose no threat to the patients’ safety. Also unlike the skin adhesion tapes, they are not subject to bonding and adhesion complications caused by the skin itself which is a living, fluid system made up of many parts.
However, diagnostic adhesives do face their own very strict restrictions created by the importance of preventing the diagnoses from being compromised. This includes ensuring total cleanliness, and avoidance of anything that might interfere with the biological and chemical processes being carried out in the devices.
For these reasons water-based acrylic or rubber-based adhesives, or any others which do not have very low levels of outgassing, VOCs and migration of adhesive components are avoided. The adhesives required must be as inert as possible, and leave as little, or no, chemical reaction residues. Instead pure acrylic or silicone adhesives without modifiers or additives are usually the choice for these pressure-sensitive adhesives and avoiding corruption of the chemical and biological processes.
The medical diagnosis adhesive tapes are used on strips (urinalysis); in lateral flow devices (pregnancy tests); micro-fluidic (blood glucose and blood testing); micro-titer plates (lab work and screening for drugs); or detecting pathogens and microbials with microwells; taking the microarray approach to genetic analysis, or using the polymerase chain reaction for PCR or DNA amplification.
Some like the pregnancy test are carried out in the home, while others are used for carrying out tests and diagnoses in medical facilities and laboratories.

Complicating it still further are the differences in the adhesives used for bonding these dissimilar metals. These adhesives, too, are not all identical. They are made up of different mixes of minerals and chemicals and only some will be suitable for bonding dissimilar metals, and particularly aluminium, without impacting negatively on the surface of the bond.
The wrong adhesive choice for bonding steel and aluminum can increase the chances of galvanic corrosion and oxidization, and electrochemical process which causes one dissimilar metal to corrode onto the other, particularly when both the steel and aluminum are in electrical contact and an electrolyte is involved.
The electrolyte allows ions to pass between the two metals, giving rise to the galvanic process and when bonding steel and aluminum, the aluminum is the biggest challenge and most likely to corrode onto the steel because Aluminum oxidizes faster, quickly producing a white powder which rapidly corrodes onto the steel.
Corrosion can also occur as a result in the presence of carbon, whether on un-primed bare metal, in moldings, clips, plastic parts and gaskets, or even be included in the adhesives used for bonding if bare aluminum comes in contact with it. While carbon has no impact on bare steel, carbon properties may react with the aluminum and cause corrosion not only between the aluminum and the steel, but also between the adhesive and the aluminum, because of their dissimilarity.
Automotive manufacturers have shown that epoxy priming followed with paint on steel can help to control the galvanic corrosion between it and aluminum by insulating it from corrosion and improving the adhesion by separating aluminum from contact with moisture and from coming in contact with other substances or chemicals which would allow for ions passing between the aluminum and the steel.

According to the researchers this build-up can in some instances lead to chronic pain; obstruction in the intestines; or even to death. They are usually caused by the body’s own built-in reaction to surgical wounds, which results in a flood of molecules targeting the tissue around the wound in a bid to heal it quickly, but which by overshooting can result in the wound being bound to healthy tissue instead, and so cause scar tissue to develop in the wrong place. They can also be the result of inserted adhesive anti-scar tissue barriers similarly missing the targeted area because of double-sided adhesives tendency to adhere to other materials; by being misplaced, or by becoming diluted when injected into the moist area around the wound.
The researchers, led by Yaobin Wu, report that the new HAD asymmetrical adhesive hydrogel is based on knowledge gathered from marine animals and contains polyanionic ligands and pure saline. Testing has shown it to be compatible with human cells, and tests conducted on rats treated with the HAD hydrogel before surgery showed no deaths, lower inflammation, and no apparent scar-tissue development over a two week period, while between 30% and 50% of untreated rats died.
According to the researchers, the asymmetric double-sided adhesive HAD hydrogel injectable has been designed to prevent the side of the adhesive hydrogel not directly in contact with the wound from drying out and adhering to other tissue. This is done by photocuring the side that’s not in contact under UV light for a few seconds to help keep the hydrogel from adhering to other materials.

The needs of different crafters differ vastly according to the type of craft involved and the specific projects undertaken. These include anything from repairing clothing to working on artistic decoupage, collages and quilts; and from mending heavy-duty fabrics used for outdoor shelter and indoor upholstery, to holding fabrics in place while sewing a seam and adding finishing touches like buttons and decorative designs to garments.
To meet these varied needs, adhesive manufacturers have provided an equally wide array of solutions, most of which provide strong bonds, are water resistant, clear, and flexible when dried. However, as they are formulated according to the specific needs of different crafts, not all are the same in formulation or application, nor in how quickly they cure. Some are presented in liquid form, while others take the form of sprays, sticks, iron-on tapes and patches.
Factors to take into account in choosing an adhesive to match a craft include consideration of the fabrics being used; the curing time for the adhesives, what substrates they will be bonded to, and whether a permanent or temporary bond is required.
Long- term bond adhesives are usually liquid, and provide bonds that will be durable enough to withstand impacts caused by the environment, over usage, regular wear, and machine washing. However, they can be hard to remove successfully in response to mistakes or changes in design. Short-term adhesives which are easy to remove and re-use, are often found in spray or stick form, or as tapes or patches.

In addition to their high adhesion properties, latex binders have selected film formations, are able to withstand harsh conditions and extreme temperatures, and are therefore resistant to electrolyte swelling, flexibility and elongation across a wide range of temperatures, which improves the battery’s life cycle. They also reduce the impact of cell impedance caused by a combination of internal electrical resistance and ionic reactance; enhance lithium-ions’ conduction rate between the electrolyte and the styrene-butadiene (SBR) film; and enhance the battery’s low-temperature performance.
While currently different binding agents are used for each battery component, including the cathode, anode and separator, a transition to one binding agent is being explored which will improve the small component’s performance still further. Aspects under consideration include enhancing binder capacity, reducing the likelihood of impurities, benefiting performance, and providing equilibrium between the binder and its environment without impacting on its high adhesion levels with its substrates.
However, until this planned single binder is developed, careful choice of the right binder product is necessary. Adhesive latex binders chosen for use with Li-ion batteries should be flexible and without brittleness to avoid cracking and problems with contacts under drying conditions or in response to the internal extension of graphite. It is also required to ensure that the binder’s elongation remains usable in preventing breaks and ruptures during the cutting and rolling process, and to maintain its ability to withstand interacting with electrolyte in pressure conditions and various temperatures so as to avoid fatigue breaks.

According to the company, the hypoallergenic silicone adhesive patch, which is placed on the upper back, is reusable up to 10 times before replacement is required. The adhesive patch, the company reports, is designed to identify incorrect postures using biofeedback technology, and to alert the wearer with gentle vibrations when their postural position needs adjustment. When the patch is synced with a compatible smartphone, the wearer is able to view a real-time image on the Upright app provided by an on-screen avatar which mimics the posture that caused the adhesive patch to issue the alert.
This sync also allows for statistics and progress records to be stored so as to chart the progression the wearer is making with regard to maintaining a straight up posture and avoiding the impact of bad posture on back health.
The company reports that two versions of the tiny adhesive patch have been developed, both working with the same principles. Both are just under 2 inches in height, 1.14 inches in width, have a depth of 0.34 inches, and are powered with rechargeable lithium-polymer battery. However they vary in terms of the number of smart sensors they have, the availability of advanced movement technology, and the number of customization plans included.

However, complicating the challenge has been the different understandings between countries, and within different industries, of the exact meaning of sustainability, its overall and specific goals, and what approach would best achieve them, while also taking into account environmental accountability as well as consumers’ requirements.
Adhesive manufacturers developing suitable adhesives and sealants are dealing with not only the industries’ needs, but also with adhering to various rules and classifications, as well as including new raw materials in the mix. These include materials such as diacids like succinic; natural oil and CO2 -based polyols; 1.4-butanediol and Bio-based-isobutanol; bio-based alternatives to isocyanate; esters and furan dicarboxylic acid; as well as bio-based epichlorohydrin; and the creation of bio-based solvents such as ethyl acetate and acetone.
The packaging industry is under the spotlight when it comes to the struggle for sustainability, with food and beverage packaging accounting for about half of the solid municipal waste. Various categories have been determined to classify new adhesives according to their performance and formulation.
Biodegradable adhesives, considered the best choice for packaging, hygiene products, and medical devices as well as for envelopes, are based on natural raw materials and renewable materials which have no petroleum derivatives in their formulation, and therefore have a lower carbon footprint. These adhesives can be broken down by living organisms such as bacteria, and (depending on the surrounding environmental conditions) can produce water, carbon dioxide, and other natural gases in the process.
Adhesives are declared “recyclable” when shown to be totally compatible with the substrates they have bonded, and can be melted down entirely without leaving waste or residue when the lifespan of the products they have bonded comes to an end. These types of adhesives are used for automotive applications, and for bonding aluminum, glass and steel.
Similarly, adhesives which dissolve completely along with the paper during repulping, without leaving residue or film behind in the process, are fitted into the “repulpable” category. Common applications are to cardboard boxes, and paper products such as envelopes.
Compostable adhesives, on the other hand, are broken down in a compost pile, and also leave no waste or residue when they are fully composted, and can be used to fertilize and improve the soil.

According to Henkel Australia, both the surveys and the workshops are aimed at ensuring those teams responsible for maintenance and repair are aware of the commonest causes of failures, including those most likely to go unnoticed. These include the impact of loose fasteners, bearing shifts and slips, and the build-up of corrosion on bearings and cylindrical parts. Solutions are then found and a proactive approach to maintenance is planned which can assist in preventing or slowing down this impact, and so lessen the amount of downtime.
The company reports that the workshops are usually split into two sessions, one of which involves identifying the applications used by the individual industry, and the other focused on adhesive solutions, and on anaerobic adhesives in particular) which could increase efficiency and reduce downtime by reducing leaks and improving seals with thread locking and sealants instead of tapes, and the advantages of liquid gaskets and retaining.

Equipment now available ranges from software through traditional test frames, force sensors, and grips and fixtures, depending on the requirements of particular tests. Choosing the right equipment and how best to use it depends on the type and objective of the force measurement test being carried out, which is in turn determined by the size of the sample and how much it is estimated to deflect or deform, and the expected maximum force involved.
With the recent increase in software testing efficiency, software teamed with traditional force gauges and test stands could be the answer to many aspects. Although the software has evolved to a level where it can integrate the force sensor into a software system with a user interface which allows it to take over designing tests for even complex applications which involve custom combinations of sequences or cyclical testing.
The right software can also analyze results and export data as well as generating reports, and display graphs of the results which assist the performance of coefficient of friction tests by showing problem areas in the display, as well as providing necessary information for specific tests in the results table for maximum force tests. However, the software has not yet reached the point at which it can take over the very challenging tasks of extracting, presenting and analyzing data.
More traditional equipment than software includes test frames for various force capacities, which can be adjusted according to the height and depth of samples used. These frames, which include a compression and tension force actuator, can be regulated to ensure tests can be repeated in accordance with the test method.
Force sensors used to measure tension and compression forces have a wide range of capacities from a low point of 50 gram force to levels of thousands of pounds force, which are selected according to an established standard of not being lower than between 5 and 10 % of the application’s requirement.
The third type of equipment revolves around grips and fixtures, now available in both generalized and designed for application-specific use.

Similar to, but stronger, than super glues, the dots which are packaged for immediate use, can provide bonds that are almost instant on substrates, which can range from posters, foams, walls, and glass, to wood and metals. The only preparation needed lies in careful removal from the packaging, and cutting the dots into shapes when necessary.
Unlike the guns, dots do not need a power source or heating prior to application or during bonding; there is no dry time as they are pressure sensitive; they leave very little mess behind, and carry less risk of injuries and application errors caused by the hot adhesive delivered by the gun.
Both dots and guns have arrays of products to match different projects and their needs, including those suitable for either long term permanent bonds or shorter term ones which can be easily removed. Choosing the right dot or gun from this wide array of variants with different abilities and sizes for individual projects, is vital to ensure successful projects.
Not all adhesive dots have the same adhesive tack and therefore do not have identical strengths or durability. Those with lower tack are best suited for smaller projects such as craft work and simple repairs unlikely to be permanent and easily removable bonds would be preferable. When the project involves heavier and more durable applications, and easy removal is not required, bigger adhesive dots with a higher tack are a better option, and more likely to provide a successful outcome.
Like the dots, the guns also differ in sizes and suitability for projects ranging from crafts and small repairs to heavy-duty bonding on a wide array of substrates that include wood, painted or unpainted wall or drywall, as well as paper, foam, metal and glass.
For crafts and easy repairs at home, mini-guns which heat up quickly and maintain heat constantly are the most suitable. As the task becomes more complex and the project needs stronger and more lasting bonds, the guns used are bigger, and higher heat levels are reached.
Glue guns produce a durable bond which will prove to be both secure and permanent provided the adhesive is correctly applied. However, applying the hot adhesive requires attachment to a power-source to provide and maintain the heat of the adhesive during application, and while the bond is fast-drying, it is not as instant as the adhesive dots which involve no dry time.

RecyClass is a cross-industry initiative that advances plastic packaging recyclability and ensures traceability and transparency of recycled plastic content in Europe. The organization aims to establish a harmonized approach toward recycled content calculation through activities such as the rigorous scientific testing and certification of innovative materials.
“To receive the RecyClass approval, our innovative SF adhesives were extensively tested in accordance with strict scientific protocols that have confirmed their suitability for the packaging recycling process,” said Guilherme Fernandes, senior manager of product development for polyurethanes at Henkel.
The Henkel solution has been tested by the RecyClass PO films Technical Committee. During the assessment, how the different solvent-free laminating adhesives impact the properties of laminated LDPE film layers after recycling was reviewed.
As a result, it has been confirmed that both solvent-free laminating adhesives are fully compatible with existing European industrial recycling processes for PE flexibles. In addition, the use of both adhesives did not have any negative impact on the quality of the recycled content and was proven to be suitable for use in applications such as PE blown films up to 25%.

Shifting from welding metal to adhesive bonding has been especially challenging because of metal’s non-porous nature and smooth surface, but three types of adhesives (epoxy, polyurethane and cyanoacrylate) are now bonding metal to metal as well as to dissimilar substrates like glass, wood, and fabric, according to their abilities to meet the specific needs of different metal bond projects.
However, many different products falling within these ranges of adhesive products not all of which are designed for metal bonding or the substrates to which it will be bonded, choosing the right one for a specific metal application needs to be based on the suitability of individual products within the range to fit the needs of each project. This information is vital, particularly when it comes to tensile strength, reactions to environmental conditions, curing times, the window for correction during application, and how easy they are to use. All are factors which can differ considerably with different adhesives.
Epoxy: For bonding metal to metal, two part epoxies made up of a separate hardener and resin, which are mixed in equal proportions, offer multiple advantages such as high tensile strength, and flexibility in the materials that can be bonded with metal. They also stand up to various temperatures, don’t conduct electricity, are waterproof, hard, and can be drilled and sanded after they are fully cured.
Some epoxies will involve more difficult and time-taking applications. Mixing the two parts before application, the surface preparation (without contamination) required by some; and the need for application on both substrates, all involve time. Initial drying can take from 5 to 30 minutes, depending on the epoxy used, and the full cure period (anywhere from 4 to 24 hours) can cause long delays. Clamping is usually recommended in the first drying period.
Polyurethane: While polyurethane adhesive metal bonds are not as strong as the epoxies and require the correct amount of heat or moisture (usually in the environment) to cure well, the expansion of coverage and gap filling abilities, are strong benefits . Polyurethanes are suitable for securing metal to other substrates, and can be used outdoors because of their high resistance to water and UV light. Polyurethane adhesives are single part adhesives, usually easy to apply and spread (with different ones requiring application to one or both substrates). There is open time for correction of mistakes before the adhesive starts to harden (around 10 minutes) provided the adhesive chosen does not have a strong grab; leaks from joints can be cleaned with a damp cloth, and when fully hardened the adhesive can be filed, chiseled or sanded.
Cyanoacrylates: When it comes to super glues, high strength versions of these polymers can also bond both metal to metal as well as to other materials in simple repairs and small tasks. This adhesive requires water in the environment to form its strong chemical chains, but its water resistance is too low for use outdoors. Applying it involves care. Using the liquid version can involve spillage, and application be difficult, while the gel version is easier to handle.

This growth rate, together with constantly expanding regulations regarding safety, standards, and compliance, has highlighted the importance of force measurement in adhesive testing, and the data it provides about components and assemblies, to ensure optimum adhesion and performance in existing and new areas while also assisting with product design, quality control, and problem solving in problematic areas.
Force measurement benefits both adhesive manufacturers and end users by lessening risks and gathering better insight into what the adhesive’s performance is likely to be like when used in any given application. This information, while valuable in most applications, becomes increasingly important (and more vital in terms of meeting compliance regulations) when being used for application in sensitive areas such as medical applications and aerospace.
Unlike materials testing, which analyzes a wide range of factors like elasticity, elongation, strain and stress, force measurement tests factors like the compression strength of adhesives (especially when adhesive tape is used) and its tensile and pull-off strength when two substrates have been bonded, to enable a projection of the performance which can be expected from the adhesive in specific applications.
Various processes are used to gather information in order to carry out force measurement testing in different situations by relying on physical motion and a collection of measurements, while others involve equipment. The first approach includes peel tests, one of which, the T-peel test, is often used for adhesive labels in the packaging sector. It focuses on the separation force of the labels to determine whether the adhesive bond is likely to separate prematurely; if the bond can hold its strength yet be easily removed at the right time; and if its performance remains consistent in different batches.
Another peel test, the loop tack test, focuses instead on how evenly the adhesive has been spread down the length of the tape or bond, as irregularity in the amount of adhesive applied in different areas can affect the integrity and performance of the bond.
The coefficient of friction test performs a completely different task. It’s focus is on coatings, where it helps quantify the coating’s frictional properties so as to ensure consistency in manufacturing regardless of whether the coating is being used to protect an object, or to bring about a required sliding resistance or tactile feel on it.

“In the 2017 Mini Transat, thanks to SAF glue, I was able to reattach the keel padeye that had torn off and gone through the deck, thus guaranteeing the water tightness,” said Quentin Vlamynck, skipper of the Arkema 4 Ocean Fifty trimaran, one of the yachts competing in the TJV race.
“On the 2015 Transat Jacques Vabre, the front of the central hull cracked following an impact,” said skipper Lalou Roucayrol. “A significant water leak in the boat forced me to pump out more than a hundred litres without managing to dry it out completely. I was able to make a makeshift repair by gluing a flexible plate on the hull with Bostik SAF methacrylate glues. This experience shows the feasibility of a repair at sea.”

The deterioration can be slowed, if not totally prevented, by applying an adhesive sealcoating. This coating, which forms a membrane that protects the substrate should preferably be done before the onset of winter, in reasonably dry weather and when temperatures are over 50° for the best result.
Careful preparation is needed prior to application. This includes clearing the driveway of vehicles, cutting away any invasive grass on its borders, and removing any shoots that are growing in, or through, the driveway itself. The next step is to wash away grease and dirt on the driveway using a general degreaser powered by a garden sprayer or pressure washer, and to remove stains left by oil or gas that might affect the sealcoating application using a strong cleaner and stiff brush. Finally, all large cracks or potholes must be filled.
The sealcoating is first applied along the borders of the driveway using a 4 inch paintbrush, and then to the inner area according to the manufacturer’s instructions.
Blocking the driveway to people and vehicles while the sealant is drying is the best way to a successful outcome. Depending on the sealant used, the drying times may differ from about one hour for a one-coat quick-dry sealant, to as long as 48 hours when the sealant requires two coats.

Adhesive bonding provides several benefits over mechanical fastening. These include the ability to at the same time join materials and seal the joint, so lessening the chance of leak paths forming and reduce the weight by using thinner gauge materials. By replacing welding, adhesives also reduce the need for abrading or refinishing and eliminate galvanic corrosion by providing electrical and thermal brakes when dissimilar metals are used in the bond.
These factors, when the correct adhesive is linked with the right amount of automation, reduce the challenges and speeds for manufacturers battling to meet growing product demand, or looking to improving consistency, precision, quality and traceability. They can also reduce the levels of waste and scrap, speed up the inventory, and cut back on labor hours.
However, the level of automation involved in individual manufacturing operations differs according to the automation that’s installed and it’s level of function. This affects both the choice of whether to make automation part of the assembly and if so, how high its level should be to meet the needs, but it also affects the scale of the adhesives that will have to be used with it.
Fortunately, adhesives are scaled to meet all four levels of automation. These levels start with manual and simple tools such as adhesive tapes and adhesive dispensers which deliver the proper ratio and followed by process assistance which uses semi-automated tools to improve the productivity of operators using hand held tools.
The third and fourth levels deal with more developed forms of automation. Fixed automation handle a single and very specific action which improves speed, consistency, and accuracy such as continuous laminators and a conveyor belt for adhesive tapes, roll coaters for dispensing the same amount of liquid adhesives onto a large area, or using certain robots.
Flexible automation, on the other hand, is made to handle various assembly processes at the same time or can be re-purposed to carry out different ones according to the need at the time. This level of automation usually incorporates robots capable of taping or dispensing adhesives.

When applying sealants, problems can arise for various reasons. These include issues such as choosing the right sealant for the application in the first place, the size of the working space available for application, and taking the correct approach to surface preparation. However, these problems can be easily dealt with.
There is a wide range of sealants with different formulations and manufactured to handle different tasks and meet the needs of different products and environments to ensure the sealant can grip properly and perform as required.
Choosing the correct sealant is affected by the material it is going to seal, and where and why it is being used. Factors such as whether the substrate is wood, metal or glass; whether the sealant needs to be water repellent or not; if it’s to be used inside or outside; or for food preparations, are all important to bear in mind before application.
Preparing the substrates for application involves making sure that, before the sealant is applied, any residue on the exposed surface is brushed off, the surface is cleaned properly with rubbing alcohol, and it is allowed to dry completely before application. When the substrates have been used previously, and the existing sealants and adhesives have to be removed, using a commercial caulk remover can ease the removal of the old applications by softening the aged applications, which can then be more easily sliced through with a knife. Protective equipment should be used and slicing done carefully to avoid damaging the surface. It can then be peeled off using needle-nosed pliers.
Other ways to simplify sealant application and ensure a good outcome require adapting the methods and equipment used. Using a straw instead of a caulk gun to apply sealant can simplify application when very little space is available (like behind a sink). The straw must fit snugly around the sealant’s tube, be cut to the right length, and have its nozzle shaped to 45°. If the cap of a silicone sealant goes astray, or there is no cap, using the sealant to seal the tube spout is easily done by making a ball of sealant and using it as a cap to avoid waste.
Using an adhesives tape on each side of the sealant application (and removing it before it is completely dry) will ensure a straight line application; clogged or blocked tubes can be saved for future use by unclogging them with a screw ; and using glass cleaner can solve the sticky sealant problem when smoothing it out after application.

The studies reviewed and analyzed included both adhesive drapes which had been impregnated with different infusions determined by the operations carried out, which included knee and hip replacements, hip dysplasia, rotator cuff repairs, and lumbar spine operations, as well as those which were not infused at all. Regardless of the differences in drapes used, all showed a similar pattern and decreased risk of wound contamination when compared with those situations in which no adhesive drapes were used.

Suitability
Suitability means there has been discernment that an adhesive is either necessary or desirable. When welding either metals or thermoplastics, the two materials to be joined must be metallurgically or polymerically compatible. That is frequently not the case when joining dissimilar metals, and it is almost always the case when joining dissimilar polymers. Even metals within the same general class (e.g., steels, aluminum) may not be metallurgically compatible, and polymers within the same class (e.g., polyethylene) may not weld to each other.
Mechanical fastening requires holes or some form of crimp/puncture, which results in poor stress distribution and the need for increased material thickness since all the load is borne by point contacts. This is often overcome by including adhesives with mechanical fasteners, which results in more even load distribution with attendant weight and material savings. It also enables the joining of dissimilar materials. In the absence of welding or fastening, adhesive bonding is the suitable choice.
Compatibility
Compatibility refers to an adhesive’s ability to bond to both surfaces. This can be an issue when joining dissimilar materials because the surface adhesion characteristics differ. Examples include joining a polymer or composite to a metal or joining different metals. Different adhesive types have differing abilities to bond to different materials.
Epoxy adhesives have been the traditional choice for bonding ceramics or metals, as well as composites. However, they are less frequently used for bonding polymers. Acrylic adhesives work well on most types of materials and are used for metals, composites, and polymers. They have lower strength and temperature resistance than epoxies.

The scientists report that new studies have discovered that the holdfast aquatic bacteria (caulobacter crescentus), discovered seven years ago by Canadian microbiologist Yves Brun of the Université de Montréal, is not alone in its strong adhesive abilities when bonding on wet surfaces like pipes and in fresh water. Their research showed that it shares genes with another bacteria (hirschia baltica), a relative which achieves similar levels of strong adhesive bonds in wet surroundings. This second holdfast, however, instead of resisting salinity as the first one did, uses salinity as its natural environment.
To boost the environmental coverage of the caulobacter bacteria’s adhesive ability to include saline water, the scientists report that they altered its composition and charge slightly by manipulating the level of expression of a particular gene. This changed the properties of both bacteria’s, and so improved the Caulobacter holdfast’s performance in a saline environment, which would make it usable as an adhesive in plumbing and hospitals where saline water is often present.
