| introduction | DMTDA is a new type of polyurethane elastomer curing crosslinking agent, in which there are mainly two isomers, namely, a mixture of 2,4-and 2,6-dimethylthio toluenediamine (the ratio is about 77~80/17~20). compared with MOCA commonly used, it is a liquid with lower viscosity at normal temperature, it can be applied to construction operation at low temperature and has the advantages of low chemical equivalent. |
| application | DMTDA is an environmentally friendly and low-toxic liquid diamine chain extender, mainly used for polyurethane elastomers, RIM (reaction injection molding),SPUA (spray polyurea elastomer) and adhesives; at the same time, it can also be used as epoxy resin curing agent. It has been widely used in polyurethane rubber rollers, medicine, stamping and other aspects. In addition, it is widely used in automobile, construction, coal mine, metal mine, textile, paper making and printing industries. |
| uses | the main uses of dimethylthio toluene diamine are: 1. it is a new type of liquid curing agent for polyurethane elastomer, which is widely used in polyurethane casting, coating, RIM, SPUA, polyurethane tire and adhesive for chain expansion or crosslinking, and is also a curing agent for epoxy resin. 2. As a hardener, when adding TDI and MTDI two-liquid polyurethane elastomers, it must be added according to the degree of 10%. In the construction and civil engineering industries, it is often used as an additive for fire prevention coating (top and side wall), anti-corrosion of metal materials (coating of inner wall of iron pipe), etc, polyurethane products that can be reacted with other substances without any treatment are better than MOCA (Mocha) hardener products. 3, used for polyurethane printing rubber scraping, oil pipe cleaning scraper, etc., improve the oil resistance of polyurethane, volume expansion rate is also low. 4. Construction, coal mines, metal mines, medicine, stamping and forming, etc. In addition, it has a wide range of applications in the textile, papermaking, and printing industries. It can be said that from the aviation and aerospace industries to the ordinary civil industries, it has It has a broad market. |
