THPA is usually used in the production of alkyd and unsaturated polyester resins,coatings and the curing agent for the epoxy resins,and also it is used in insecticides,sulfide regulator, plasticizers, surfactant, etc.
As raw materials for the production of unsaturated polyester, THPA mainly improved the air-drying performance of resins.The performance is more obvious especially in the production of high-grade resin putty and air-drying coatings.
