EP resin - epoxy resin

The resin component is prepared by condensation and addition of epichlorohydrin and a divalent or multivalent phenol derivative. The reaction between these two raw materials produces the epoxy resin. The epoxy group found twice in each molecule of the resin is highly reactive and can react with appropriate substances called hardeners. Polyamines and polyamides are most commonly used as hardeners. These substances are able to open the ring at the epoxy group by possessing reactive hydrogen atoms. The curing process is an exothermic reaction, so heat is released. for more info, see:

Epoxy or polyepoxide is a chemical compound. It is an epoxide polymer composed of 2 carbon atoms (C) and 1 oxygen atom (O) in a ring-shaped structure. Epoxy distinguishes itself from polyester by, for example, greater flexibility, the fact that it adheres to almost any surface and the fact that it yellows under the influence of UV and therefore has to be finished with UV-resistant lacquer. for more information, see
