Menene Dimethyl thio-toluene Diamine DMTDA?

DMTDA wani sabon nau'i ne na maganin elastomer na polyurethane da wakili na crosslinking, wanda akwai yawancin isomers guda biyu, wato cakuda 2,4 - da 2,6 - dimethylthiotoluene diamine (rabo shine game da 77 ~ 80/17 ~ 20). Idan aka kwatanta da MOCA da aka saba amfani da shi, DMTDA ruwa ne mai ƙarancin danko a yanayin zafi na al'ada, wanda za'a iya amfani dashi don aikin gini a ƙananan zafin jiki, kuma yana da ƙarancin sinadarai daidai.
