Epoxy Acrylates （EA）
Epoxy acrylate (EA) is the most widely used and most widely used light curing oligomer. It is prepared by the reaction of epoxy resin and (meth) acrylate. Epoxy acrylates can be divided into bisphenol A epoxy acrylates, phenolic epoxy acrylates, epoxidized oil acrylates and modified epoxy acrylates according to different structural types. Bisphenol A epoxy acrylates are the most commonly used and the largest amount is used. However, there are some problems in this kind of products, such as poor flexibility of curing film, high brittleness, poor adhesive force, high viscosity and so on At the same time, the light aging resistance and yellowing resistance are poor, so many times we will use its modified products;
