2. Polyurethane Elastomers for Industrial Flooring

Polyurethane flooring system producers use this amine derivative as a chain extender and crosslinker during prepolymer and polyol blending stages, where it significantly enhances tensile strength and chemical resistance of the cured elastomer. System adjusters rely on its strong catalytic activity to balance the reactivity of isocyanates, especially for two-component and self-leveling screeds. Its exact ratio is crucial to managing pot life under varying ambient temperature and humidity. Downstream QC departments often require test panels to qualify the mechanical and surface properties before launch.
