[0002] Epoxy resin is a high molecular polymer, which refers to a general term for a class of polymers containing two or more epoxy groups in the molecule. It is the condensation product of epichlorohydrin and bisphenol A or polyols. Due to the chemical activity of the epoxy group, it can be opened with a variety of compounds containing active hydrogen, and cured and cross-linked to form a network structure. Therefore, it is a thermosetting resin. Bisphenol A type epoxy resin not only has the largest output and the most complete varieties, but also new modified varieties are still increasing and the quality is constantly improving. Epoxy resin is a polymer material with good physical properties and chemical stability, usually composed of epoxy resin monomer and curing agent.
