What is Dimethyl thio-toluene Diamine DMTDA?

Dimethyl thio-toluene diamine (DMTDA), with the CAS number 106264-79-3, is an important organic compound. The sulfur atoms in the DMTDA amine molecule can enhance the coordination ability with metals, and at the same time endow the cured product with excellent hydrolysis resistance and chemical corrosion resistance.

DMTDA is a new type of polyurethane elastomer curing and crosslinking agent, in which there are mainly two isomers, namely the mixture of 2,4 – and 2,6 – dimethylthiotoluene diamine (the ratio is about 77~80/17~20). Compared with the commonly used MOCA, DMTDA is a liquid with low viscosity at normal temperature, which can be used for construction operation at low temperature, and has low chemical equivalent.

Application

1. Dimethyl thio-toluene diamine is a new type of liquid curing agent for polyurethane elastomer. Dmtda amine is widely used in polyurethane casting, coating, RIM, SPUA, polyurethane tire and adhesive for chain extension or cross-linking, and is also a curing agent for epoxy resin.

2. Dmtda ethacure 300 is a curing agent for epoxy resin and can be used to improve the performance of epoxy resin.

3. As hardener, when added to TDI and MTDI two-liquid polyurethane elastomers, it must be added at the rate of 10%. In the construction and civil industry, dmtda amine is often used as an additive for fireproof coating (layer top and side wall), corrosion protection of metal materials (coating on the inner wall of iron pipe), and other aspects. The polyurethane product that can react with other substances without any treatment is superior to the product of MOCA (Mocha) hardener.

4. Used for polyurethane printing rubber scraper, oil pipe cleaning scraper, etc., to improve the oil resistance of polyurethane, and the volume expansion rate is also low.

5. In addition, dmtda amine is widely used in the textile, paper and printing industries. Dimethyl thio-toluene diamine can be said that it has a broad market from the aviation and aerospace industry to the general civil industry.
