产品介绍
Product description
Methyl hexahydrophthalic anhydride is refined from the catalytic hydrofining of methyl tetrahydrophthalic anhydride, methyl hexahydrophthalic anhydride, MHHPA.
Main features
Light colorIt is a colorless transparent body, soluble in benzene, acetone, etc., and the epoxy cured substance is white.
Good heat resistanceIt has good weather resistance, is not affected by light and heat, and has good moisture resistance; it has high reactivity, can be cured quickly, and the gel time is short.
Many advantagesIt has the advantages of low melting point, low viscosity of the complex composed of alicyclic epoxy resins, long application period, high heat resistance of the cured material, and good high temperature electrical properties.
Main purpose
Mainly used as an epoxy resin curing agent, MHHPA is a heat-curing acid anhydride curing agent, mainly used in the electrical and electronic fields, can be used for the impregnation of electrical equipment coils, the casting of electrical components and the sealing of semiconductor, such as outdoor insulators, capacitors, light-emitting diodes, etc., digital tubes, etc.
