Applications
As crosslinking agent or curing agent, MOCA can be applied in the production of machines, buildings, automobiles, airplanes, mining and sport equipments, or used in the curing of epoxy resin.
Including:
1. Suitable for PU products cast by casting machine such as: wheel of sliding way, rubber rollers, lining of mold, swirler, driving belt, coupling, screen cloth, and sealing products;
2. Curing of epoxy resin and epoxy urethane resin.
MOCA consumption calculation
wm=Prepolymer(kg)*NCO%*3.18*f/100
f=0.95
Q: what is the consumption of MOCA by kg of 5kg prepolymer with NCO% 5.0?
A:Wm=5*5.0*3.18*0.95/100=0.755kgs
