Application

Hexahydrophthalic Anhydride (HHPA) is a saturated dicarboxylic anhydride widely used in adhesives, sealants, industrial chemicals, coatings, and paints. It serves as a monomer in resin manufacturing, an intermediate in chemical synthesis, and a hardener for epoxy resins, with availability in both liquid and flake forms. HHPA is a white, low-melting solid (38 °C) that is miscible with most organic solvents and hydrolyzes in water to form hexahydrophthalic acid. Its reactivity is typical of compounds in its class, making it a versatile material for industrial applications.
