Product Usage:
1、As solidifying agent for epoxy resins: MHHPA is heating-solidification type acid anhydride solidifying agent, mainly used in electrical and electronic field, with low melting point, the compounding matter with alicyclic epoxy resin is of low viscosity, long use life, excellent heat resistance and high-temperature electric properties, can be used in dipping of coil of electric apparatus, casting of electric parts and sealing of semiconductor.
2、As adhesive: the alicyclic epoxy adhesive made from MHHPA has similar refractive index as optical glass, low internal stress after solidifying, high adhesion strength, color unchangeable, resistance to aging, applicable for cohering large-area optical parts. 
3、As insecticide, plasticizer and antirust, etc.
