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.
