Tetrahydrophthalic Anhydride(THPA)

CAS # [935-79-5]

MF ：C₈H₈O₃

FW ：152.16

Spec ：White flaky solid,>99%

Structure：

Use：As an organic intermediate,THPA is usually used in the production of alkyd and unsaturated polyester resins,coatings and the curing agent for the epoxy resins,and also used in insecticides,sulfide regulator, plasticizers, surfactant, alkyd resin modifier,pesticides and the raw materials of pharmaceuticals. 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.

Properties

Cis-1,2,3,6-Tetrahydrophthalic Anhydride is a new organic anhydride based epoxy curing agent with excellent properties, used in alkoxylic and unsaturated resins, which can improve the adhesion, elasticity, gloss and water resistance of coatings. As a plasticizer, PVC increases cold, heat resistance, and is nontoxic. In the electronics and electricity industry, aerospace field is widely used. Meanwhile this product is also the raw material of synthetic surfactants, pharmaceutical pesticide products.
