Description
Aminoethylethanolamine (AEEA, CAS 111-41-1) is a bifunctional amine combining a primary amine and a hydroxyl group within a single molecule. Also referenced as N-(2-Aminoethyl)ethanolamine and Hydroxyethyl-ethylenediamine, it carries no assigned E-code and is classified under HS code 29221980.
In epoxy coatings and adhesives, AEEA acts as a crosslinker and curing agent, reacting with epoxide groups to build network structures that improve mechanical and chemical resistance. In textile and paper processing, its dual functionality supports pH buffering and delivers antimicrobial activity by disrupting microbial cell membranes. It also serves as a reactive intermediate in flame-retardant polymer formulations.
AEEA is supplied as a neat liquid and is subject to REACH registration requirements within the EU. Procurement teams should confirm supplier SDS documentation and purity specifications prior to sourcing. Standard packaging formats for industrial supply typically include drums and intermediate bulk containers.
