DMTDA CAS 106264-79-3

short description:

DMTDA is a new type of polyurethane elastomer curing cross-linking agent, DMTDA are mainly two isomers, 2,4- and 2,6-dimethylthiotoluenediamine mixture (the ratio is about Chemicalbook77~80/17 ~20), compared with the commonly used MOCA, DMTDA is a liquid with lower viscosity at room temperature, DMTDA can be suitable for construction operations at low temperature and has the advantages of low chemical equivalent.

Applications

DMTDA is an environmentally friendly and low-toxic liquid diamine chain extender, mainly used in polyurethane elastomers, RIM (reaction injection molding), SPUA (spray polyurea elastomers) and adhesives; at the same time, Chemicalbook can also be used as epoxy resin Curing agent, has been widely used in polyurethane rubber roller, medicine, stamping and other aspects, in addition, it has a wide range of applications in automobiles, construction, coal mines, metal mines, textiles, papermaking, and printing industries.

  1. It is a new type of liquid curing agent for polyurethane elastomers. It is widely used in polyurethane casting, coatings, RIM, SPUA, polyurethane tires and adhesives for chain extension or crosslinking. It is also a curing agent for epoxy resins.
  2. As a hardener, when added to TDI and MTDI two-component polyurethane elastomers, it must be added at a level of 10%. ), anti-corrosion of metal materials (coating of the inner wall of iron pipes) and other chemicalbook additives, the polyurethane products obtained by reacting with other substances without any treatment are superior to the products of MOCA (Mocha) hardener.
  3. It is used for polyurethane printing squeegee, oil pipe cleaning scraper, etc., to improve the oil resistance of polyurethane, and the 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, paper, and printing industries. It can be said that it is used in aviation, aerospace, and ordinary civilian industries. broad market.
