Used as a crosslinking agent in polyurethane systems, particularly in coatings and adhesives where enhanced durability and chemical resistance are required. Its structure allows for controlled reactivity, making it suitable for two-component systems that cure at ambient or elevated temperatures. Commonly applied in high-performance industrial finishes and elastomers due to its ability to improve mechanical strength and thermal stability. Also utilized in specialty sealants where extended pot life and strong adhesion to substrates are critical.
