Methyl tetra-Hydro Phthalic Anhydride(MTHPA) has been used in the curing agents for epoxy resins, solvent-free paints, laminated boards epoxy adhesives and so on.

When used in the curing agent for epoxy resins, there are many excellent performances such as the long-term storage at room temperature, low freezing point, low volatility and low toxicity. Also widely used in motors, dry-type transformers, high voltage switches, transformers, line-output transformers, appliances capacitors, integrated circuits impregnation, casting and winding
