Applications: Methyltetrahydrophthalic Anhydride (MTHPA) has been used as the curing agents for epoxy resins, solvent-free paints, laminated boards epoxy adhesives and so on. When used as the curing agent for epoxy resins, there are many excellent performances such as the longer-term storage at room temperature, lower freezing point, lower volatility and lower toxicity. Also it is widely used in motors, dry-type transformers, high voltage switches, transformers, line-output transformers, appliances capacitors, integrated circuits impregnation, casting and windin
