Photo-Curing Schemes to Cure the Epoxy Resins and their Impacts on Curing Process

Abstract

Different schemes to photo-cure the epoxy resins are reviewed in this article. Photo curing of epoxy resin by UV-polymerization mechanism is one of the effective methods. "A light induced chemical practice to cure the dry composites i.e. coatings or films are the termed as photo curing". The most important fact of photo curing is that it gives best performance, eco-friendly compatibility, and efficacy of processing. So, due to these facts, thermal curing is replaced by photo curing. Photo curing is applicable only for the films of definite thickness and colored composites. Epoxy resin and photo initiator were mixed together and then mixtures were cured through a curing reaction which was proceeded in the presence of infrared or ultraviolet light (UV-Light), or an electron beam.
