Ethylenediamine (EDA) is the simplest aliphatic amine epoxy hardener — a small, highly reactive diamine that gives fast ambient cure and is also a key building block for larger ethyleneamines. Identity: CAS 107-15-3.
What it is
Ethylenediamine (CAS 107-15-3) is a low-molecular-weight diamine (supplied here as the ethyleneamines E-100 grade). It is highly reactive and also the parent of DETA, TETA and higher ethyleneamines.
How it cures
Its primary-amine hydrogens ring-open epoxide groups to crosslink the resin; the small molecule gives fast room-temperature cure and a rigid, high-crosslink network, though with limited pot life and the usual aliphatic-amine handling cautions.
Applications
EDA is used as an epoxy hardener and as a building block in adhesives, coatings and chemical synthesis. Higher ethyleneamines give longer pot life and toughness: TETA and AEEA.
Forms, grades and handling
EDA is supplied as a clear liquid in drums, IBCs and bulk. Properties are typical reference values; the Certificate of Analysis (CoA) for the lot you buy governs. Amine curing agents are typically corrosive and can sensitize skin — handle per the current Safety Data Sheet (SDS). Each lot ships with CoA, TDS and SDS.
Bulk supply and RFQ
RawSource sources Ethylenediamine direct from producers in bulk, with CoA, TDS and SDS per lot. Tell us your resin system, cure schedule (ambient or heat) and the properties you need (pot life, Tg, flexibility, chemical resistance), and we will quote the right hardener. See selection logic in the epoxy curing agents guide.

Regulatory restriction status
Ethylenediamine (EDA) (CAS 107-15-3) appears on the regulatory list(s) below. This is public regulatory information about the substance — not a statement about any specific supplier’s material, and not a safety claim. Confirm the current status for your jurisdiction and intended use.
- REACH SVHC Candidate List (EU): listed 27 Jun 2018 on the basis of respiratory sensitiser (Art. 57(f)). SVHC status triggers EU supplier-communication and notification duties above 0.1% w/w; it is not, by itself, a ban on sale.

Frequently Asked Questions
What is ethylenediamine (EDA) used for?
Ethylenediamine (EDA, CAS 107-15-3) is a fast-curing aliphatic amine epoxy hardener and a building block for higher ethyleneamines, used in adhesives, coatings and synthesis.
How is bulk ethylenediamine supplied and quoted?
RawSource supplies ethylenediamine in bulk with CoA, TDS and SDS per lot. Pricing is quote-based on grade and volume; submit an RFQ with your resin system and cure schedule.
What is the REACH and TSCA regulatory status of Ethylenediamine (EDA)?
Ethylenediamine (EDA) (CAS 107-15-3) 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 203-468-6).
