Name: Methylhexahydrophthalic anhydride, MHHPA,
Methyl-1,2-cyclohexanedicarboxylic anhydride, mixture of
isomers.
Product No: B1031 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 25 kg plastic drums or 220kg iron drums.
Transport: Hazard Class 8, Packing Group II.
Cautions: Store in cool, dry places and keep away from fire
and moisture.
