Brief Introduction:
HHPA is a white solid,soluble in benzene and acetone, moisture adsorption.Compared with THPA, hexahydrophthalic anhydride has light color and luster, low viscosity, small volatility, low toxicity, small loss on heating, stable performance, long using life, low freezing point and can be long-term stored at room temperature.
It is mainly used to the synthesis of polyester resin and normal temperature curing alcohol acid resin, also use as epoxy resin coating curing accelerator, which can improve curing speed.
