CHARACTERISTICS AND USES:
MOCA-HR is a special MOCA grade features with color stability at high temperature.The color of the
melted MOCA-HR has no big change after being heated several times,even though the heating
temperature is up to 150℃.It is recommended applied in a variety of casting polyurethane elastomer
parts especially manufactured with casting machines.The products have a lighter color.
MOCA is a kind of widely used high cost effective aromatic diamine chain extender or curing agent for
Casting polyurethane elastomers.The PU elastomers with excellent properties are widely applied in the
areas including machinery,buildings,vehicles&transportation,mining industry,electronic components
encapsulation and sports facilties,etc.
MOCA can also be used to solidify epoxy resin.
