of Switzerland, which went on to become one of the three major epoxy resin producers worldwide. Claims of discovery of bisphenol-A-based epoxy resins include Pierre Castan in 1943. History Ĭondensation of epoxides and amines was first reported and patented by Paul Schlack of Germany in 1934. The health risks associated with exposure to epoxy resin compounds include contact dermatitis and allergic reactions, as well as respiratory problems from breathing vapor and sanding dust, especially when not fully cured. for chips on board ), LEDs, high-tension electrical insulators, paint brush manufacturing, fiber-reinforced plastic materials, and adhesives for structural and other purposes. Epoxy has a wide range of applications, including metal coatings, composites, use in electronics, electrical components (e.g. Reaction of polyepoxides with themselves or with polyfunctional hardeners forms a thermosetting polymer, often with favorable mechanical properties and high thermal and chemical resistance. These co-reactants are often referred to as hardeners or curatives, and the cross-linking reaction is commonly referred to as curing. The IUPAC name for an epoxide group is an oxirane.Įpoxy resins may be reacted ( cross-linked) either with themselves through catalytic homopolymerisation, or with a wide range of co-reactants including polyfunctional amines, acids (and acid anhydrides), phenols, alcohols and thiols (usually called mercaptans). The epoxide functional group is also collectively called epoxy. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. Structure of the epoxide group, a reactive functional group present in all epoxy resinsĮpoxy is the family of basic components or cured end products of epoxy resins.
