      With polyurethane cool development, industrialization in the early 1980s and the extensive use of a hindered aromatic diamine chain extender, low viscosity, non-toxic, odorless liquid. Diethyltoluenediamine is toluene diamine (TDA) and ethylene as raw materials in the presence of a catalyst, high temperature and pressure occur G alkylation reaction, and refined.DETDA supplier in China is still small, the real production plant is not a lot DETDA.

      Diethyltoluenediamine for polyurethane products can improve the strength and hydrolysis resistance, so that products greatly improve productivity, and the large size and complex structure of polyurethane products industrialization possible. DETDA isocyanate vinegar faster reaction speed is also particularly suitable for solvent-free, fast-curing coatings. In addition, also as epoxy, alkyd resin curing agent, rubber antioxidant oils, dyes, pesticides intermediates, is a promising new chemical products. Diethyltoluenediamine much attention to the world, competing with developed DETDA chain of polyurethane products, the amount increasing every year. In the United States and Western Europe automotive RIMPU products are used almost the Diethyltoluenediamine.

      1. Introduction
   DETDA Chemical Name Diethyltoluenediamine, equivalent to Ethancure 100 and Lonza DETDA 80. Is a very effective chain extender of polyurethane elastomers, particularly suitable for RIM (reaction injection molding) and SPUA (spray polyurea elastomer) on; epoxy resin for a polyurethane elastomer and an aromatic diamine curing agent, with for casting, coating, RIM and adhesive is polyurethane and polyurea elastomer chain extender, but also can be used as polyurethane and epoxy resin curing agent, epoxy resin of antioxidants, lubricants and other industrial oils and .

5, the product uses
DETDA is a very effective chain extender of polyurethane elastomers, particularly suitable for RIM (reaction injection molding) and SPUA (spray polyurea elastomer) on; also be used as a polyurethane elastomer and the aromatic epoxy resin diamine curing agent, used for casting, coating, RIM and adhesive is polyurethane and polyurea elastomer chain extender. DETDA is a sterically hindered aromatic diamine, ethyl and methyl steric hindrance such that its activity is much lower than that of toluene diamine (TDA). It is the reaction rate of the polyurethane prepolymer is several times faster than DMTDA, about 30 times faster than MOCA. Mainly for RIM polyurethane systems and spray polyurethane (urea) elastomer coating systems, with fast response, ejection time is short, high initial strength, hydrolysis products, heat and so on. In addition, this product can also be used as elastomers, lubricants and industrial oils of antioxidants, and chemical synthesis intermediates.
