Application & Function

Methyl tetra-Hydro Phthalic Anhydride (MTHPA) 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:

- Light color when curing ,suitable for white or colorless transparent products;
- Good heat resistance, higher Tg point.
- Faster curing speed , saving the amount of promoter;
- Larger viscosity, moisture absorption higher than the general MTHPA, shall be sealed.
