What is Diethylenetriamine?
Diethylenetriamine (CAS 111-40-0), commonly abbreviated as DETA, is a polyamine building block used in adhesive, coating, and polymer manufacturing.
Where is Diethylenetriamine used?
- Epoxy systems: room-temperature curing agent for coatings, flooring compounds, and structural adhesives
- Polymer synthesis: monomer for polyamide resins and imidazoline derivatives used in corrosion inhibitors and fuel additives
- Textile and paper processing: production of wet-strength resins and softening agents that improve substrate durability
- Personal care: DETA-derived intermediates in conditioning agents and chelating systems for rinse-off and leave-on products
- Its multiple reactive amine groups make it a functional intermediate for curing agents and chemical synthesis.
Good to know: Controlled crosslink density determines final film hardness and chemical resistance in these applications. Buyers requiring tighter amine content or color specifications can source material against defined CoA parameters.
Commercial specifications
- Technical grade, purity typically 99% minimum
- Drum, IBC, and bulk tanker quantities
