What is Aminoethylethanolamine?
Aminoethylethanolamine (CAS 111-41-1), abbreviated AEEA, is a bifunctional amine-alcohol. Also known as monoethanol ethylenediamine.
Where is Aminoethylethanolamine used?
- Coatings and adhesives: curing agent and crosslinker for epoxy systems, contributing to film hardness and adhesion in industrial finishes
- Textile and leather: intermediate for softeners, fixatives and antistatic treatments
- Flame retardants: reactive intermediate incorporated into the polymer matrix
- Paper treatment: pH buffer and wet-strength resin intermediate
- Its primary amine and hydroxyl group make it a building block for curing agents, crosslinkers and pH-buffering intermediates.
Good to know: Buyers should confirm moisture content and amine value when qualifying suppliers.
Commercial specifications
- Purity typically 98–99% minimum
- Clear to pale yellow liquid in drums and IBCs
- Bulk tanker options for high-volume procurement
