Used as a crosslinking agent in polyurethane and polyurea systems, enhancing mechanical strength and thermal stability of coatings, adhesives, and elastomers. Its dual isocyanate functionality enables the formation of durable, flexible networks in specialty polymers. Commonly applied in high-performance materials requiring chemical resistance and long-term durability, such as industrial coatings and sealants. Also utilized in controlled environments for synthesizing advanced functional materials and in research for developing novel polymer architectures.
