What is Bis(hexamethylene)triamine?
Bis(hexamethylene)triamine (CAS 143-23-7), also known commercially as Bis(6-aminohexyl)amine, is a trifunctional aliphatic amine.
Where is Bis(hexamethylene)triamine used?
- Epoxy coatings and adhesives: hardener
- Polyamide and polyurea synthesis: chain extender or monomer
- Metalworking fluids and lubricant additives: corrosion inhibitor that chelates metal ions
- Sealant formulations: controlled cure rates and flexibility in moisture-resistant systems
- Its three reactive amine groups form dense network structures in thermoset systems and coordinate with metal surfaces to suppress corrosion.
Commercial specifications
- Technical grade, purity typically 98% or higher
- Bulk quantities in drums and IBC containers; smaller packaging for laboratory and specialty formulation customers
