Abstract
Low VOC thermosetting polyester acrylic resins are made by esterification of unsaturated epoxide such as glycidyl methacrylate, and a polyacid which is the half-ester formed by reacting an acid or its anhydride with a polyol is disclosed. The obtained low viscosity resin is useful for making a low or zero VOC gel coat with excellent hydrolytic and weather resistance.
