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. Unlike non-reactive amine catalysts, its hydroxyl group allows it to chemically bind into the polymer matrix. This chemical structure significantly reduces amine emissions in the finished product. In flexible and rigid polyurethane foam systems, it balances gel and blow reactions, giving formulators control over cell structure and processing window.

Coatings and adhesive formulations use it where low-emission catalyst performance is required to meet VOC compliance standards. In sealant and elastomer systems, the reactive nature of the catalyst supports durability requirements. The catalyst prevents migration over time, ensuring the integrity of the polymer. Formulators also select it for systems where residual amine odor or fogging is a disqualifying factor, particularly in automotive interior and construction applications.

The product is supplied as a liquid, typically in bulk drums or intermediate bulk containers suited to industrial-scale polyurethane processing. Technical grade is the standard commercial offering for this material. Purity specifications are aligned to polyurethane catalyst market requirements. Buyers sourcing for sensitive end-use markets such as automotive or low-emission building products should confirm emission test compliance data with the supplier.
