MFA Acc. #: 1989.818


A series of thermosetting polymers based on the chemical reactivity of an epoxide group. Epoxies, first patented in Switzerland in 1939 by Pierre Castan, were further developed in the 1940s and 50s. They are composed of a liquid that, when mixed with a catalyst, crosslinks to form a hard, strongly bound solid. The most commonly used epoxies are made with epichlorohydrin reacted with bisphenol A. Epoxies are typically dense, insoluble structures that are dimensionally stable and wear resistant. Exhibitng minimal shrinkage with cure, they are used as adhesives, molded products, and baked enamel surface coatings. Some commercial brands that contain epoxies are: Ablebond, Araldite, CM Bond, Epon® , Epotek, Hxtal, Phillyseal R (formerly Pliacre) and UHU.
