    Methy Tetra-Hydro Phthalic Anhydride 11070-44-3

    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.

    Modified Methyltetra-Hydro Phthalic Anhydride 25550-51-0

    Modified Methyl tetra-Hydro Phthalic Anhydride was used in the curing agents for epoxy resins, dry-type transformers, high voltage switches, mutual inductors, condensers, LED, etc. Relative to the general MTHPA, this specification have the following characteristics: 1. Light color when curing, suitable for white or colorless transparent products; 2. Good heat resistance, higher Tg point; 3. Faster curing speed, saving the amount of promoter; 4. Larger viscosity, moisture absorption higher than the normal MTHPA, shall be sealed.
