Hexahydrophthalic Anhydride HHPA CAS 85-42-7
Hexahydrophthalic Anhydride (HHPA), with CAS number 85-42-7, is a commonly used aliphatic epoxy resin curing agent. It is colorless, weather-resistant, has low viscosity and does not yellow. Alicyclic compounds do not contain benzene rings, are resistant to ultraviolet rays and have good weather resistance without yellowing; their melt viscosity is low and the processability is good; they are prone to hydrolyze into hexahydro-2-methylphenylphthalic acid when exposed to water (sensitive to moisture absorption).
