“Epoxy Hybrid Adhesives”
~ by Edward M. Petrie
High levels of performance are required for adhesives used for demanding structural applications in industries like aerospace. Epoxy adhesives can be used to provide good adhesion and processing characteristics, but they can also be blended with other resins to provide additional properties improvements.
A variety of polymers, both thermosets as well as thermoplastics, can be blended and co-reacted with epoxy resins. The most common of these are nitrile, phenolic, nylon, polysulfide, and polyurethane
Hybrid resins can be used to improve flexibility, thermal shock resistance, elongation, heat distortion temperature, and impact strength of epoxy adhesives. However, there can also be some sacrifice in certain physical properties due to the characteristics of the additive. Take a look at Ed Petrie's article to know more!
