Use |
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: ①Light color when curing ,suitable for white or colorless transparent products; ②Good heat resistance, higher Tg point. ③Faster curing speed , saving the amount of promoter; ④Larger viscosity, moisture absorption higher than the general MTHPA, shall be sealed. |
Packing | 25kg/barrel, 220kg/barrel, 1200kg/barrel |
Storage | This product shall be airtight, out of the sun, moisture-proof and away from het .The storage period commonly is one year. |
