What is Diethyltoluenediamine CAS 68479-98-1?
Diethylmethylenediamine is usually a mixture of two isomers (approximately 76% of 3,5-dioctyl-2,4-diaminotoluene and 24% of 3,5-dioctyl-2,6-diaminotoluene). This structure endows it with some key properties:
Good compatibility: It can well dissolve with polar organic solvents such as polyether and polyester polyols, which makes it easy to be processed in the formulation.
Moderate solubility: Slightly soluble in water. The solubility at 30℃ is approximately 23 grams per liter.
Stable physical properties: Its density is approximately 1.022 g/cm³, with a relatively high boiling point of around 308-310°C and a flash point exceeding 140°C. This indicates that it is relatively stable at room temperature, but it should be kept away from high temperatures and open flames.
Diethyltoluenediamine CAS 68479-98-1 Use
Diethylmethylenediamine can be used in polyurethanes, which can enhance the strength and hydrolytic resistance of the products, significantly increase the production efficiency of the products, and make it possible to industrialize large-sized and structurally complex polyurethane products.
Used as a curing agent for waterproof coatings
