Industrial grade99% Dimethyl thio-toluene diamine CAS 106264-79-3

Certificate of Analysis-COA 

 Applications 

1. Curative For Cast Polyurethane Elastomers: Cast PU processors charge it as the diamine curative at room temperature or after preheating between 25 and 100 degrees Celsius, and parts cured with it reach mechanical and dynamic performance comparable to established MOCA systems.

2. Chain Extender For RIM And Spray Polyurea: In reaction injection moulding of polyurethane urea, spray polyurea elastomers and adhesives it extends the polymer chain, with a reactivity that sits between MOCA and DETDA so processors can balance demould time against working life.

3. Cure Rate Tailoring By Blending With DETDA: It cures much more slowly than DETDA, so formulators blend the two liquids in different ratios to dial the cure speed to the line, extending pot life whenever degassing and mould filling need more time.

4. Aromatic Amine For Epoxy Systems: Distributors list DMTDA in epoxy alongside its urethane applications, where the aromatic amine serves as the hardener for epoxy resin systems that need high temperature performance.
