Application

1.Epoxy resin curing agent: MHHPA is a heat curing type acid anhydride curing agent. It is mainly used in electrical and electronic fields. It has good high temperature and electrical performance. It can be used for the immersion of electrical equipment coils and the casting of electrical components and semiconductor sealing. Casting outdoor insulators, light-emitting diodes (LEDs), ignition coils, special-purpose capacitors, transformers, motors, sports and entertainment equipment, etc., which are required to resist outdoor ultraviolet light and moisture resistance. 2.Epoxy composites: in combination with fiber reinforcement in lamination, centrifugal casting, pultrusion, etc., such as pressure cylinders, pressure pipes, fishing rods, golf clubs, etc. 3.Adhesive: The refractive index of alicyclic epoxy adhesive made of MHHPA is similar to that of optical glass. It has small internal stress after curing, high bonding strength, no discoloration and aging resistance. It is suitable for bonding large-area optical parts.
