Diethyl toluene diamine (DETDA) is a liquid aromatic organic molecule[2] with formula C11H18N2.

Chain extenders (f = 2) and cross linkers (f ≥ 3) are low molecular weight amine terminated compounds that play an important role in polyurea compounds, elastomers and adhesives.

DETDA is one such amine and is used extensively in reaction injection molding (RIM) and in polyurethane and polyurea elastomer formulations.

[12] Pyrolysis in combination with other materials can produce a carbon-based molecular sieve.

[18] Epoxy formulations based on DETDA also tend to have good high temperature properties.
