Product overview

A mixture of diethyltoluene diamine isomers, that is, a commercial mixture of two isomers: 3,5-diethyl-2,4-diaminotoluene (3,5-Diethyl-toluene-2,4- diamine) 76% and 3,5-diethyl-2,6-diaminotoluene (3,5-Diethyl-toluene-2,6-diamine) 24%, referred to as DETDA.

It is light yellow to reddish brown transparent liquid with ammonia smell at room temperature, slightly soluble in water, soluble in alcohol, ether, ketone and other polar organic solvents, and has good compatibility with polyether and polyester polyols.

Long-term exposure to the air will darken the color.

Diethyltoluenediamine is flammable and highly corrosive.

Skin and eye contact can cause irritation and severe burns.

Applications

Diethyltoluene diamine is used as chain extender for reaction injection molding polyurethane, curing agent for polyurethane coating, epoxy resin and alkyd resin. Pesticides, dye intermediates, plastics, rubber, oil antioxidants.

Diethyltoluene diamine is an aromatic diamine curing agent for polyurethane elastomers and epoxy resins, used for casting, coatings, adhesives, and chain extenders for polyurethane and polyurea elastomers. It has a fast reaction speed with polyurethane prepolymer, and is mainly used for reaction casting polyurethane system and spray polyurethane (urea) elastic coating system.
