Advantages
MOCA-HR features with high temperature resistance and color
stability. The color of the melted 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℃.
Applications
MOCA-HR is an aromatic diamine chain extender or curing agent for
polyurethane. It can be applied in a variety of casting polyurethane elastomer parts
manufactured with casting machines. It makes the product with light color.
MOCA-HR can also be used as curing agent for epoxy resin.
Packaging
50kg net weight in carton drum with black polyethylene liner.
