China Methyltetrahydrophthalic Anhydride, Mthpa for Industrial
Product Description
Methyl Tetrahydro Phthalic Anhydride
CAS No.: 11070-44-3
EINECS: 234-290-7
Molecular Formula: C9H10O3
Molecular Weight: 166.18
Flash Point: 140°C
Features:
1 High purity and light luster: Can be used to prepare colorful epoxy resin solidifier.
2 Low viscosity: It is easy to be casted and sealed, while casting, plenty of fillers are acceptable, thus can improve the quality of finished product.
3 Good stability: the duration is longer and the freezing point is much lower. It can be stored at room temperature for long time.
4 Low volatility: Low toxic, it is just 2.5% of amine solidifier in toxicity. Low loss on drying.
