MOCA-HR is a high temperature resistance grade, so it has outstanding
colour stability. The colour of the melting MOCA-HR liquid keeps
light-yellow and clear transparent without any changes after
heating or reheating several times, even though the heating
temperature is up to 150℃.
MOCA-HR is a aromatic diamine chain extender or curing agent for
polyurethane. It is recommended used in a variety of casting
polyurethane elastomer parts manufactured with casting machines.
MOCA-HR is also can be used in curing epoxy resin.
