Request SDS →Triethylene glycol diamine (2,2'-(ethylenedioxy)diethylamine, CAS 929-59-9) is a short-chain, fast-reacting polyether diamine. The compact, ether-linked backbone gives high reactivity, making it useful as a reactive chain extender and curing agent. Established applications are in polyurea systems and epoxy formulations where rapid cure is required.

Frequently Asked Questions
What is triethylene glycol diamine used for?
Triethylene glycol diamine is a short-chain, fast-reacting polyether diamine used as a reactive chain extender and curing agent. Its high reactivity makes it a cure-speed modifier in polyurea systems and a fast-curing amine in epoxy formulations where rapid set is required.
What is the chemical identity of this product?
This product is 2,2'-(ethylenedioxy)diethylamine, also called triethylene glycol diamine, CAS 929-59-9, with molecular formula C6H16N2O2. The compact, ether-linked backbone is what gives it high reactivity compared with the longer polymeric grades.
Why does triethylene glycol diamine react faster than longer polymeric polyether diamines?
Triethylene glycol diamine is a short, discrete diamine with primary amine groups separated by a compact ethylene-dioxy bridge, so the amine groups are highly accessible and there is little chain bulk to slow reaction. The longer polymeric grades cure more slowly because of higher molecular weight and steric effects.
What packaging and order quantities are available for bulk triethylene glycol diamine?
RawSource supplies triethylene glycol diamine to manufacturers in drums, IBC totes and bulk volumes. Available pack sizes and minimum order quantity depend on current sourcing; request a bulk quote with your target volume and destination.
Can you provide a CoA and SDS for triethylene glycol diamine?
Yes. A Certificate of Analysis for the supplied lot and the current Safety Data Sheet are provided with each order. Request both with your quote so you can confirm identity (CAS 929-59-9) and handling information before purchase.
What is the REACH and TSCA regulatory status of Triethylene Glycol Diamine?
Triethylene Glycol Diamine (CAS 929-59-9) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 224-207-2).
