  • Hexahydro-4-MethylPhthalic Acid Anhydride , Methylhexahydrophthalic Anhydride
Product Details:

Methylhexahydrophthalic anhydride Organic Acid Anhydride MHHPA for electrical and electronic fields

 


Description

 

MHHPA is a thermo - setting epoxy resin curing agent mainly used in electric and electron field. With the many advantages, e.g. low melting point, low viscosity of the mixtures with alicyclic epoxy resins, long applicable period, high heat-resistance of the cured material and excellent electrical properties at high temperature, MHHPA is widely used for impregnating electrical coils, casting electricity components and sealing semiconductors, e.g. outdoor insulators, capacitors, light emitting diodes and digital displays.

 

 

Usage

 

Mainly used in the epoxy curing agent. MHHPA is heating - curing type of anhydride curing agent, mainly used in electrical and electronic fields, having the advantages of low melting point, low viscosity of complexes with the alicyclic epoxy resin, long life, high heat resistance, good high-temperature electrical equipment coil and casting of the electrical components and seal of the semiconductors such as outdoor insulators, capacitors, LED, digital tubes.
