1.Dimethyl toluene diamine
（1）Diethyl toluene diamine(DETDA) is equivalent to Ethacure 100 and Lonza DETDA 80.It is a very effective polyurethane elastomer chian extender,and widely used as curing agent of Polyurethane and epoxy resin,epoxy resin anti-oxygen agent,chain extender for casting,coating,RIM,adhesive,industrial oil and lubricant.
（2）In addition,it also can be used as an intermediate for organic synthesis.
2.Dimethylthio toluene diamine
（1）DMTDA is a new type of polyurethane elastomer curing crosslinking agent, equivalent to Ethancure-300. Mainly includes two kinds of isomers, 2,4-isomer and 2,6-isomer (The ratio is about 77~80% / 17~20%).
（2）Compared with MOCA, DMTDA is low viscosity liquid under normal temperature, can be used in low temperature.
（3）The curing speed of DMTDA is much slower than that of DETDA, which can be mixed with DETDA in different proportions, to adjust the curing speed to meet different requirements.
