We have a problem maintaining adhesion to two steel surfaces at divergent temperatures because of the response of materials to thermal conditions when going through heating and cooling cycles.
We are using epoxy adhesives to bond steel substrates that are exposed periodically to both 150˚C and as low as 0˚C. Our problem is in maintaining adhesion to the two steel surfaces at such divergent temperatures because of the response of materials to thermal conditions when going through heating and cooling cycles. Do you have any suggestions?
Called thermoset polyesters, these materials are glass fiber-reinforced unsaturated polyesters. They are also often referred to as “sheet molding compounds” (SMCs), “fiber-reinforced plastics” (FRPs), or simply “fiberglass.”
When implemented correctly, adhesives and sealants can play a critical role in improving equipment reliability and lowering maintenance and operational costs.
Adhesives and sealants are an essential component of every equipment maintenance and reliability plan. With rapidly developing technologies and products, businesses need to stay on top of these trends. When implemented correctly, adhesives and sealants can play a critical role in improving equipment reliability and lowering maintenance and operational costs.
Vehicle manufacturers are improving fuel economy while reducing emissions by lightening the overall weight through material replacement. Using thermoplastics and adhesives instead of traditional screws and metals create less weight.
The technology comes as global regulatory single-use plastics bans go into effect across the globe.

H.B. Fuller has launched a new generation of high-performance adhesives with Swift® tak 5730 grade to create consumer-safe, liquid-resistant paper straws.
I have worked with companies that manufacture superglue and polyurethane glue, both of which are single-component, no-mix adhesives. Superglue, which is the common term for cyanoacrylate adhesive, has been around for about 60 years. In contrast, the polyurethanes are about 20 years old in the retail market and somewhat older in professional woodworking. I admit to using both types of adhesive regularly.
A new system comprising a curing oven, regenerative thermal oxidizer (RTO), and secondary and tertiary heat exchangers can help reduce operating costs while ensuring the safe removal of volatile organic compounds during composite bonding processes.
Among all chemical curing techniques, convection and radiant thermal curing represent the most widely used applications for adhesives and sealants. During the curing process, adhesives and sealants usually pass through two physical transformations—evaporation and condensation—while being applied to other materials.
