Product Description
4MHHPA is produced by hydrogenation from MTHPA.
It is used mainly as a hardener for epoxy resin.
To compare with amine hardener, 4MHHPA is low viscosity liquid of light color and low in volatility.
Potlife is considerably longer than amines.
Electrical and mechanical properties of cured resins compare favorablywith these based on amine hardeners. 4MHHPA is hydroscopic and should be protected from light and moisture.
