Usage

 

1. It can be used as modifier of alkyd resin, epoxy resin curing agent, unsaturated polyester resin, pesticide and pharmaceutical raw materials

 

2. As intermediates in organic synthesis, four hydrogen of benzene anhydride are commonly used to produce alkyd resins and unsaturated polyester resin, paint, also used as the curing agent of epoxy resin, and also used in pesticide, sulfide regulator, plasticizer, surface active agent and so on. As a raw material for producing unsaturated polyester resin, tetrahydrobenzene is mainly used to improve the air drying of the resin, especially in the production of high grade resin.

  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.
