Methylhexahydrophthalic anhydride, MHHPA,
Methyl-1,2-cyclohexanedicarboxylic anhydride, mixture of isomers.
CAS No: 25550-51-0 Formula: C9H12O3
Formula Weight: 168.19
Properties: Soluble 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.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.
Package: Packed in 20 kg or 220kg iron drums.
Transport: Hazard Class 8, Packing Group II.
Cautions: Store in cool, dry places and keep away from fire and
