Applications:

1. Curing agent or hardener for epoxy resins: 4-MHHPA is heating anhydride curing agent, it is widely used in electric and electronic industry by the process of impregnating, casting and sealing, such as casting outdoor insulator, LED, ignition coil, capacitor, transformer, motor and sport appliances. It has low melting point, low viscosity, long pot life, and the condensate has high performance of heat resistance and electrical properties.
2. Composite materials of epoxy matrix: 4-MHHPA has been widely used in high performance composite materials, along with fiber reinforced materials by process of spun casting, pultrusion, filament winding, such as pressure cylinder, pressure pipeline, golf clubs and fishing rod.
3. Adhesives: the cured product has similar refractive index to optical glass. it has little internal stress, high bond strength, antifade and anti-ageing. It is suitable for optical parts bonding of large area.
