3,3 -Dichloro-4,4 -diaminodiphenylmethan

Some aromatic diamines used as curing agents, such as 4,4 diaminodi-phenyl derivatives or 3,3 Dichloro 4,4 diaminodiphenylmethane (MOCA), have been investigated and have been declared to have suspect carcinogenic properties. All local rules and regulations must be adhered to if these materials are used.

It should be stressed that the viscosity changes during formation of polyurethanes even from bifiinctional compounds can be correlated with gelation most likely they are connected with the formation of a physical network then crosslinks arise from sufficiently strong specific interactions like hydrogen bonds [50]. An example of such a process is the reaction of macro (diisocyanate) with 3,3 -dichloro-4,4 -diaminodiphenylmethane [43]. 

TIN, TIN FLAKE, or TIN POWDER (7440-31-5) Finely divided material is combustible and forms explosive mixture with air. Contact with moisture in air forms tin dioxide.
