Diethyl toluenediamine (DETDA), is also commonly known in the polyurethane industry by the brand names Ethacure 100, Lonza DETDA 80, and Nitroil ADA I80.
One of the commonly used workhorses in polyurethane industry, DETDA has low viscosity and is easy to handle. 
Diethyltoluenediamines unmatched liquidity character enables manufacturers to perform room temperature processing and curing. 
DETDA also offers excellent dynamic properties comparable to 4,4'-Methylenebis(2-chloroaniline), also known as MOCA, but with less toxicity and dust concerns in the production plant. 
Diethyltoluenediamines fast curing leaves little room for environmental factors like humidity and oxidation to affect the quality of products featuring DETDA.
DETDA is widely used in reaction injection molding (RIM) and the spray polyurea field.  
In these applications, DETDA allows the flexibility of using itself as a liquid carrier and solvent for other solid curatives like MOCA, for example, and makes Diethyltoluenediamine possible to bring variety of needed properties into the final product.
