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.
