Used as a crosslinking agent in polymer chemistry, particularly in the production of high-performance resins and thermosetting materials. It enables the formation of stable three-dimensional networks by reacting with nucleophilic groups in polymers, enhancing thermal stability, mechanical strength, and chemical resistance. Commonly applied in coatings, adhesives, and electronic encapsulants where durability under harsh conditions is required. Also utilized in specialty curing systems for epoxy and unsaturated polyester formulations, offering controlled reactivity and improved processing characteristics.
