Used primarily as a crosslinking agent in polyurethane systems, this compound enhances the mechanical strength and thermal stability of coatings, adhesives, and elastomers. Its multiple isocyanate groups react with polyols to form durable, resilient polymer networks. It is especially effective in high-performance applications requiring resistance to abrasion, chemicals, and elevated temperatures. Commonly found in industrial coatings and specialty sealants where long-term durability is critical.
