Used primarily as a crosslinking agent in the production of polyurethane coatings, adhesives, and elastomers. It enhances the durability, chemical resistance, and mechanical strength of the final products. Commonly applied in industrial coatings for automotive, aerospace, and construction sectors due to its ability to form robust, weather-resistant films. Also utilized in the manufacture of high-performance adhesives for bonding materials in demanding environments. Its reactivity with polyols makes it a key component in creating flexible or rigid foams used in insulation and cushioning applications.
