N,N,N′-Trimethyl-N′-hydroxyethylbis(aminoethyl) ether

N,N,N′-Trimethyl-N′-hydroxyethylbis(aminoethyl) ether (CAS 83016-70-0) is a reactive tertiary amine catalyst used in polyurethane foam production.

Where is N,N,N′-Trimethyl-N′-hydroxyethylbis(aminoethyl) ether used?

• Flexible and rigid polyurethane foam: balances gel and blow reactions, giving control over cell structure and processing window
• Coatings and adhesives: low-emission catalyst performance for VOC compliance
• Sealants and elastomers: reactive nature supports durability
• It prevents migration over time, preserving polymer integrity.
• Automotive interior and construction: selected where residual amine odor or fogging is disqualifying

Good to know: Unlike non-reactive amine catalysts, its hydroxyl group allows it to chemically bind into the polymer matrix, significantly reducing amine emissions in the finished product. Buyers sourcing for sensitive end-use markets such as automotive or low-emission building products should confirm emission test compliance data with the supplier.
