Hexahydrophthalic anhydride (CAS No. 85-42-7), with the molecular formula C8H10O3, is a cycloaliphatic anhydride that appears as a white or colorless solid or molten liquid. It is widely used as a curing agent for epoxy resins. Compared to aromatic anhydrides, HHPA offers lower melting points, reduced viscosity in epoxy formulations, and excellent electrical insulation properties. The cured products exhibit good mechanical strength, heat resistance, and weather ability.
