Chemical name: Methyltetrahydrophthalic anhydride CAS：26590-20-5 11070-44-3 EC：247-830-1

This product is a new type of fine chemical product that is indispensable for electronic industry and electromechanical industry products. Widely used in potting, casting, encapsulation, lamination, molding, bonding, winding and other processes. Epoxy resin curing agent: electronic and electrical insulating materials (VPI motor impregnation/dry-type transformer/transformer casting/high voltage switch/capacitor), LED digital tube potting glue, jewelry coating (crystal drop plastic polishing glue), glass fiber reinforced plastic composite material (CNG cylinders/wind turbine blades/electrical casing), etc.

1、 High purity and light color: epoxy resin products of various colors can be directly prepared or modulated into desired colors.

2、Low viscosity: The processability of casting, potting and dipping is good, and a large amount of filler can be added during casting to make the cured product excellent in performance.

3、Stable performance, low freezing point, long pot life: it can be stored for a long time at room temperature.

4、Low volatility: low toxicity; small heating loss, toxicity is only one-twentieth to one-fortieth of amine curing agents.

5、Good mutual solubility: This product is compatible with all epoxy resins, with low mixing viscosity and low system shrinkage during heating and curing.
