Tetrahydrophthalic Anhydride(THPA)Application:
As an intermediate of organic synthetic raw materials, tetrahydrophthalic anhydride is generally used to produce alkyd resin, unsaturated polyester resin, coating, curing agent of epoxy resin, insecticide, vulcanization regulator, plasticizer and surface activator, modifier of alkyd resin, pesticide and pharmaceutical raw materials.
As the raw material of unsaturated polyester resin, the main purpose is to improve the air drying property of the resin, especially in the production of high-grade resin putty and air drying coatings.
