DETA, also known as diethylene triamine, bis(2-aminoethyl)amine, or N-(2-aminoethyl)ethane-1,2-diamine, is a low-molecular-weight polyamine corresponding to CAS 111-40-0 and commonly used in epoxy resin curing systems. Its functionality is based on multiple primary and secondary amine groups that react with epoxide rings, enabling crosslinking and network formation in resin formulations, and it is also applied as a reactive component in wet strength agent production. The material is supplied with competitive factory pricing, customized specifications, complete documentation including MSDS, TDS, COA, and consistent bulk supply.

Product Description
Product Overview
Diethylenetriamine is provided for industrial use as a reactive polyamine intermediate. Its multiple amine groups make it suitable for curing systems, resin processing, gas treatment chemistry, and downstream synthesis routes that require strong amine reactivity.
This product is more appropriately positioned as an industrial chemical and intermediate rather than a finished end-use formulation ingredient. Product selection is generally based on identity consistency, purity level, moisture control, and compatibility with the intended process system.
