Hexahydro-4-methylphthalic anhydride (CAS: 19438-60-9) is an alicyclic dicarboxylic anhydride with low viscosity, low vapor pressure, and reduced toxicity relative to aromatic anhydrides. As an epoxy curing agent, it yields cured networks with excellent heat resistance, electrical insulation, and weatherability, widely used in electronic encapsulation and laminates.
