Advantages
MOCA-HR is characterized by excellent high-temperature resistance
and color stability. Even after multiple heating and reheating
cycles at temperatures up to 150 °C, the melted MOCA-HR remains
light yellow, clear, and transparent, with no noticeable change in
appearance.
Applications
MOCA-HR is an aromatic diamine chain extender and curing agent for
polyurethane systems. It is suitable for use in a wide range of
cast polyurethane elastomer components produced with casting
machines, providing a light-colored final product. Additionally,
MOCA-HR can be used as a curing agent for epoxy resins.
Packaging
50kg net weight in carton drum with black polyethylene liner.
