Dimethyl Thio-Toluene Diamine - DMTDA（Ethancure 300 ）

DMTDA

DMTDA is an eco-friendly low-toxicity liquid aromatic diamine chain extender, equivalent to Ethancure300, including 2 kinds of isomers, that is, the mixture of 2,4- and 2,6 -DMTDA (proportion: 77~80/17~20). It reacts with NCO slower than DETDA and can be applied to cast polyurethane elastomers, and can also be used with DETDA to adapt to different application scenarios.
