N,N-Bis(3-dimethylaminopropyl)isopropanolamine

N,N-Bis(3-dimethylaminopropyl)isopropanolamine (CAS 67151-63-7) is a tertiary amine compound used as a reactive catalyst and crosslinker in polyurethane and polymer systems.

Where is N,N-Bis(3-dimethylaminopropyl)isopropanolamine used?

• Polyurethane foam and elastomer production: balanced blow and gel catalyst
• Flexible and rigid foam formulations: control of cell structure and processing window
• Adhesives and sealants: cure accelerator in two-component polyurethane systems where migration must be minimized
• Coatings: reactive hydroxyl group allows incorporation into the crosslinked matrix, reducing volatile amine content in the cured film
• Polymer compounding: building block for specialty polyols
• Custom resin synthesis: amine-functional intermediate
• Its amine and hydroxyl functionality allows it to participate directly in the polymer network.

Good to know: Unlike a purely fugitive catalyst, it accelerates cure by reacting into the polymer network.

Commercial specifications

• Typically supplied in drum and IBC quantities
• Buyers should confirm amine value and hydroxyl number against their specific formulation requirements.
