Epoxy Adhesives


Epoxy adhesives are thermosetting resins which solidify by polymerization and, once set, will soften but not melt on heating. Two-part resin/hardener epoxy systems solidify on mixing (sometimes accelerated by heat), while one-part epoxy adhesives require heat to initiate the reaction of a latent catalyst.

Explore advancements in the new structural epoxy adhesives (high lap shear strength at sub-ambient temperature, toughness and high hot/wet glass transition temperature Tg retention…).
