Applications：Modified Methyltetrahydrophthalic Anhydride is used as the curing agents for epoxy resins, dry-type transformers, high voltage switches, mutual inductors, condensers, LED, etc. Compared with the general MTHPA, this modified MTHPA has the following characteristics:
1. Lighter color when curing, suitable for white or colorless transparent products;
2. Better heat resistance, higher Tg point;
3. Faster curing speed, saving the amount of promoter;
4. Larger viscosity, higher moisture absorption, it should be sealed.
Packaging: 25kg/barrel, 220kg/drum, 1100kg/IBC, ISO tank
Storage: This product shall be airtight, out of the sun, moisture-proof and away from heat. The storage period is one year.
