Different combinations of other curatives could partially substitute for TMP. 

MBCA (commonly referred to as MOCA) is a special diamine that has worked very well as a curative for TDI-terminated prepolymers. MBCA was first introduced in the mid-1950s for high-performance polyurethane applications. However, the use of MBCA has been restricted because this curative has been found to be a carcinogen requiring special handling to protect workers. 

Several thousand tons of MOCA are still used in many countries worldwide.
