Unsaturated polyester resin is a chemical compound obtained by condensation of unsaturated acids, anhydrides, and polyols. Processing of these resins also involves the use of other raw materials such as initiators, stabilizers, surfactants, and fillers. Unsaturated polyester resins have good crosslinking properties and provide stability to the finished product. Furthermore, these resins have high tensile strength, good fatigue limits, and strong heat and chemical resistance. These resins are used in the manufacture of various end-user products and materials such as cement composites, artificial stone, marine components, automotive body parts, electrical wires, gel coats, and sheet molding materials.
