Used as a chain extender in polyurethane and polyurea systems, particularly in high-performance elastomers and coatings. Offers excellent reactivity and processing characteristics, making it ideal for reaction injection molding (RIM) applications. Provides superior mechanical properties, chemical resistance, and thermal stability in the final polymer product. Commonly used in automotive, industrial, and protective coating applications where durability and performance under stress are critical. Also serves as a curing agent for epoxy resins, enhancing toughness and impact resistance.
