Used as a crosslinking agent in polyurethane systems to enhance durability, chemical resistance, and mechanical strength. Commonly applied in high-performance coatings, adhesives, and sealants where improved adhesion and long-term stability are required. Its trifunctional isocyanate groups react with hydroxyl or amine groups, forming robust networks ideal for industrial and automotive finishes. Also utilized in elastomers to increase resilience and abrasion resistance.
