What is Tetramethyldipropylenetriamine?
Tetramethyldipropylenetriamine (CAS 6711-48-4) is a tertiary triamine used as a catalyst and curing agent in polyurethane and epoxy systems.
Where is Tetramethyldipropylenetriamine used?
- Polyurethane foam and elastomer production: blowing and gelling catalyst influencing cell structure and mechanical properties
- Epoxy systems: curing or co-curing agent where extended pot life and moderate cure temperatures are required
- Adhesives and sealants: crosslinking in two-component formulations targeting structural bonding
- Lubricants and metalworking fluids: corrosion inhibitor intermediates or additive precursors
- It supports controlled reactivity in polymer formulations.
Good to know: Handle according to standard safety protocols for industrial amines; store in a cool, dry, well-ventilated facility.
Commercial specifications
- Purity typically 98% or higher for catalyst applications
- Packaging ranges from drums to IBC totes depending on order volume
