TECNICAL DATA SHEET

MHHPA is a heat-curing anhydride curing agent widely used in the electrical and electronics industries. It features a low melting point, long pot life, high heat resistance, and excellent high-temperature electrical properties. It is also used for impregnation of electrical equipment coils, casting of electrical components, and sealing of semiconductors, such as light-emitting diodes (LEDs), ignition circuits, special-purpose capacitors, transformers, and motors.

l Epoxy Composites

MHHPA is increasingly used in high-performance composites. Its application in combination with fiber-reinforced materials in lamination, centrifugal casting, and pultrusion is gaining increasing attention. Applications include pressure gas cylinders, pressure piping, fishing rods, and golf clubs.

l Adhesives

Cycloaliphatic epoxy adhesives made with MHHPA have a refractive index like that of optical glass. After curing, they exhibit low internal stress, high bond strength, stable color, and excellent aging resistance, making them suitable for bonding large-area optical components.
