Epoxy resin CAS 61788-97-4

Epoxy resin, abbreviated as EP, is a general term for resins containing two or more epoxy groups in the molecular structure. No matter how long or short the molecule is, both ends of the bond are basically epoxy groups, and the functionality of the epoxy group is 2. After cross-linking and curing with a curing agent, a three-dimensional network structure can be formed, so epoxy resin is a kind of Body type polymer compound. According to the degree of polymerization, it can be divided into liquid or solid state. Since the epoxy group is a three-membered ring, this three-membered ring is easy to open and has strong reactivity, and many characteristics of epoxy resins are derived from this. The most important variety of epoxy resins is the bisphenol A type glycidyl ether epoxy resin formed by the polycondensation of epichlorohydrin and bisphenol A; Oxygen resin.
