Dimethylthiotoluenediamine

Dimethylthiotoluenediamine (CAS 106264-79-3, EC 403-240-8) is an aromatic diamine curing agent commonly known by the trade name Ethacure 300 and abbreviated as DADMT. It belongs to the amine chemical category and carries the molecular formula C9H14N2S2.

In polyurethane and polyurea elastomer systems, DADMT reacts with isocyanates to extend polymer chains and form crosslinked networks, producing materials with high load-bearing capacity and abrasion resistance. It is also used in epoxy formulations for aerospace and automotive components where controlled cure kinetics and mechanical durability under stress are required.

DADMT is supplied in compliance with REACH regulations applicable to the European market. It is available for procurement in standard industrial drum and IBC packaging formats suited to formulation-scale operations. Buyers should confirm grade specifications and SDS documentation with the supplier prior to ordering.
