Methylhexahydrophthalic Anhydride (MHHPA)

Low melting point, low viscosity of the mixtures with alicyclic epoxy resins, long applicable period, high heat-resistance.

Name: Methylhexahydrophthalic anhydride, MHHPA, Methyl-1, 2-cyclohexanedicarboxylic anhydride, mixture of isomers.

Product NO.: B1015

CAS NO.: 19438-60-9, 85-42-7

Formula.: C9H12O3

Formula Weight: 168.19

Properties: Solube in benzene, acetone, etc. Sensitive to moisture. Specific gravity 1.162.

Application: MHHPA is a thermo-setting epoxy resin curing agent mainly used in electric and electron field. With the many advantages, e.e. low melting point, low viscosity 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, lioght emitting diodes and digital displays.
