Kedu ihe bụ Dimethyl thio-toluene Diamine DMTDA?

Dimethyl thio-toluene diamine (DMTDA), nke nwere nọmba CAS 106264-79-3, bụ ihe dị mkpa sitere na organic. Atọm sulfur dị na molekul amine DMTDA nwere ike ime ka ikike nhazi ya na ọla dịkwuo mma, ma n'otu oge ahụ nye ngwaahịa a gwọrọ nke ọma na iguzogide hydrolysis na iguzogide corrosion kemịkalụ.

DMTDA bụ ụdị polyurethane elastomer curing and crosslinking agent ọhụrụ, nke nwere isi isomers abụọ, ya bụ ngwakọta nke 2,4 – na 2,6 – dimethylthiotoluene diamine (nkezi ya dị ihe dịka 77~80/17~20). Ma e jiri ya tụnyere MOCA a na-ejikarị eme ihe, DMTDA bụ mmiri mmiri nwere obere viscosity na okpomọkụ nkịtị, nke enwere ike iji rụọ ọrụ owuwu na obere okpomọkụ, ma nwee obere nhata kemịkalụ.
