Applications
Pyromellitic dianhydride is used as a monomer in the preparation of polyimide polymers such as kapton; thermoplastics such as polyesters, polyethers, plasticizers, and expoxy resins. It is involved in the preparation of high performance coatings due to its mechanical, thermal and oxidative stability properties. It acts as a curing agent for epoxy resins which find application in adhesives, coatings and molding powders. As an intermediate, it plays an important role in polyimide based materials like printed circuit boards, tape automated bonding and magnetic wire insulation.

Solubility
Soluble in dimethyl sulfoxide, acetone, chloroform, ethyl ether, n-hexane and benzene.

Notes
Moisture sensitive. Store in cool place. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with alcohols and strong oxidizing agents.
