Product Details
Introduction
Dimethyl Thio-Toluene Diamine is a new type of polyurethane elastomer curing crosslinking agent, which mainly contains two isomers, namely a mixture of 2,4- and 2,6-dimethylthiotoluene diamine (the ratio is about 77~80/17~20). Compared with the commonly used MOCA, it is a liquid with lower viscosity at room temperature, can be used for construction operations at low temperatures, and has the advantages of low chemical equivalent.
