WebPhoto 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. WebA new approach for the cure-on-demand of coatings involves the photo-generation of a base catalyst, which then causes resins to crosslink and cure via a base-catalysed mechanism. The advantage of using a photolatent base catalyst is to be able to cure a wide range of conventional coatings at low temperatures. The influence of different parameters on the …
