Article illustration

Diethyltoluenediamine is light yellow to amber transparent liquid. Diethyltoluenediamine isan excellent and low cost chain extender for elastomeric polyurethanes (PU) and also a curing agent for epoxides (EP). In addition it may be used as an intermediate for organic syntheses. Diethyltoluenediamine is a kind of steric aromatic diamine chain extender, a low-viscosity, non-toxic, odorless liquid. In PU, it can enhance the product's strength and hydrolysis resistance, which enhances the production efficiency and makes the industrialization of complex PU products impossible. Quick reaction speed of Diethyltoluenediamine and isocyanate is particularly applied to solvent-free, fast-curing coating. Moreover, Diethyltoluenediamine also can be used as epoxy, alkyd resin curing agent, rubber and oil antioxygen, dye and pesticide intermediate, and is a kind of new promising chemical product.

Diethyltoluenediamine is mainly applied to RIM PU system and PU (urea) elastomer coating system, with quick reaction speed, short demoulding time, high initial strength, hydrolysis resistance, heat resistance, etc. Moreover, Diethyltoluenediamine also can be used as the elastomer, chain extender for reaction injection moulding PU, PU coating, epoxy resin, and alkyd resin curing agent. lubricant and pesticide, dye intermediate, plastic, rubber, oil antioxygen, and chemical synthetic intermediate. Diethyltoluenediamine is identical to Ethancure 100 and Lonza DETDA 80, Diethyltoluenediamine is very effective polyurethane elastomer chain extender; Diethyltoluenediamine also is used as polyurethane and epoxy resin curing agent, epoxy resin of an antioxidant, industrial oils and lubricants.

In addition, Diethyltoluenediamine also is used as intermediates in organic synthesis. Especially for the RIM (reaction injection molding), is important in the field of spray polyurea chain extender species. Diethyltoluenediamine also can be used for casting polyurethane elastomer (CPU) and a curing agent, epoxy curing agent, epoxy resin of antioxidants, lubricants and industrial oils other antioxidants. Diethyltoluenediamine is kept in the seal room and kept under low temperature and dry condition.
