Methyl Tetrahydrophthalic Anhydride

Methyl tetrahydrophthalic anhydride (abbreviation: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, appliances capacitors, power capacitors, integrated circuits impregnation, casting and winding.
