Main application fields:

1. Epoxy resin curing agent: MHHPA is a heat curing anhydride curing agent, which is widely used in the electrical and electronic industries. It has the characteristics of low melting point, long application period, high heat resistance of cured products and good high-temperature electrical properties. It can also be used for the impregnation of electrical equipment coils, the casting of electric gas components and the sealing of semiconductors, such as LED, ignition line diagram Special purpose capacitors, transformers, motors, etc.

2. Epoxy matrix composites:It is more and more widely used in high-performance composites. Together with fiber reinforced materials, it has attracted more and more attention in lamination, centrifugal casting, pultrusion molding and so on. Such as pressure cylinders, pressure pipes, fishing rods, golf clubs, etc.

3. adhesive: the epoxy resin adhesive made of MHHPA has similar refractive index with optical glass. After curing, it has small internal stress, high bond strength, stable color and aging resistance. It is suitable for bonding large area optical parts.
