Methyltetrahydrophthalic anhydrideProperties
Methyl tetrahydrophthalic anhydride is of high purity and light color. It can be directly prepared or prepared into epoxy resin products of various colors required.
Low Viscosity: Casting, filling and impregnation process is good. When casting, a large number of fillers can be added, so that the properties of cured products are excellent.
It has stable performance, low freezing point, long service life and can be stored at room temperature for a long time.
Low volatility: low toxicity; low heating loss, toxicity is only one twentieth to one fortieth of amine curing agent.
Mutual solubility: This product can be soluble with all epoxy resins, low mixing viscosity, while heating curing system shrinkage is small.Description of necessary first-aid measures
