Was ist DMTDA Cas 106264-79-3?
Dimethyl Thio-toluene Diamine (DMTDA), also known as Ethacure 300 or DMTDA Amine, is a liquid aromatic diamine curative widely used for polyurethane (PU) elastomers, polyurea coatings, and epoxy systems.
With moderate reactivity, excellent mechanical properties, and good processing flexibility, DMTDA has become one of the most popular alternatives to MOCA and other conventional aromatic diamines.
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 amine is a liquid with low viscosity at normal temperature, DMTDA amine can be used for construction operation at low temperature, and has low chemical equivalent.

Anwendung
1. Dimethyl thio-toluene diamine is a new type of liquid curing agent for polyurethane elastomer. It 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. Als härter, wenn die TDI-und MTDI zwei-Flüssigkeit Polyurethan-Elastomeren, es muss Hinzugefügt werden, in Höhe von 10%. In der Bau-und ziviler Industrie, es ist oft verwendet als additive für Feuerfeste Beschichtung (Schicht oben und an der Seitenwand), Korrosionsschutz von Metall-Material (Beschichtung auf der inneren Wand der Eisen-Rohr), und andere Aspekte. Die Polyurethan-Produkt, dass können reagieren mit anderen Substanzen ohne Behandlung überlegen ist das Produkt von MOCA (Mocha) - härter.
3. Verwendet für Polyurethan-Druck-Gummi-Spachtel, öl-Rohr-Reinigungs-Schaber, etc., zur Verbesserung der öl-Beständigkeit von Polyurethan, und die Volumen expansion rate ist ebenfalls gering.
4. Ethacure 300 (DMTDA) is widely used in electronic encapsulation and potting compounds due to its low viscosity, thermal stability, and uniform curing behavior.
It improves electrical insulation, thermal shock resistance, and longevity of the encapsulated parts.
5. In addition, Dimethyl thio-toluene diamine 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.
