As the intermediate of organic synthesis raw materials, tetrahydrophthalic anhydride is generally used to produce alkyd resin, unsaturated polyester resin, coating, curing agent of epoxy resin, insecticide, curing regulator, plasticizer and surface activator, modifier of alkyd resin, pesticide and pharmaceutical raw materials, etc.
Tetrahydrophthalic anhydride, as the raw material for the production of unsaturated polyester resin, mainly improves the air dryness of the resin, especially in the production of high-grade resin atomic ash and air dry coating.
