DETDA is equal to Ethacure 100 and Lonza DETDA 80. DEDTA is the short name of diethyl toluene diamine.
It is a very effective chain extender of polyurethane elastomer, in particular for RIM (reaction injection molding) and SPUA (Spray Polyurea Elastomer).
Moreover, DETDA (similar to Ethacure) can also be used as a curing agent of polyurethane and epoxy resin, antioxidant of epoxy resin, industrial oil, and lubricants.
In addition, the diethyl toluene diamine can also serve as intermediates in organic synthesis.
