TDI Curatives 4 4 Methylene Bis 2 Chloroaniline Melting Range 98℃ -
Chemical Name: 4,4'-methylene-bis-(ortho-chloroaniline) (MOCA)
CAS No.: 101-14-4
High temperature resistance particle MOCA means in the entire
process of dissolution, the solution of MOCA always keeps light
yellow, clear and transparent without changing the color of the
solution even when the temperature reaches 150℃ or it is dissolved
repeatedly for several times. Because of the high temperature
resistance property of this MOCA, this kind of product is most
suitable for various PU products molded by casting machine.
MOCA as crosslinking agent or curing agent is widely used in
machinery, construction, automobile manufacturing, aircraft
manufacturing, mining industry and sports facility manufacturing,
which can also be used for curing epoxy resin.
1. Suitable for machine casting PU products, such as skateboard
wheels, all kinds of rubber-covered rollers, mold lining,
Cyclone, driving belt, coupling, screen cloth, sealing articles,
2. The curing of epoxy resin.
1. Waterproof kraft paper bags, lined with black plastic; 25 kg.
2. Cardboard barrel, lined with black plastic bag; 50kg.
