Epoxy vinyl ester resins (VER), Often shortened to vinyl esters, are an important class of high-performance thermoset molding resins. They are produced by the addition of α - β unsaturated carboxylic acids to epoxy resins. The two main types of epoxy resins are bisphenol A diglycidyl ether (DGEBA) and epoxy phenol novolac (EPN).
