Dimethyl Thio-Toluene Diamine(DMTDA) is a new polyurethane elastomer cured crosslinking agent, which is equivalent to Ethancure 300 mainly 2,6-thio-toluenediamine mixture of two isomers i.e., 2,4- and (ratio of about 77 ~ 80/17 ~ 20), compared with MOCA commonly used at room temperature is low viscosity liquid, it can be applied to construction operations, chemical use and low equivalent at low temperatures. DMTDA is an environmentally friendly low-toxicity liquid type diamine chain extenders, mainly used for polyurethane elastomers, RIM (reaction injection molding), SPUA (spray polyurea elastomer) and adhesives; also be used as an epoxy resin curing agent, has been widely used in polyurethane rubber roller, medical, stamping, etc. in addition, it is in the automotive, construction, mining, metal mining, textiles, paper, printing industry has a wide range of applications. DMTDA curing rate is much slower than DETDA, with DETDA mixed in different proportions to regulate the curing speed to meet different needs.
