Used as a crosslinking agent in polymer chemistry, particularly in the development of functional coatings and adhesives. It enables efficient coupling between polymers containing nucleophilic groups such as amines or hydroxyls, enhancing film formation and mechanical strength. Commonly applied in water-based systems where controlled reactivity and good storage stability are required. Also utilized in biomedical materials for modifying surfaces or immobilizing biomolecules due to its ability to form stable covalent bonds under mild conditions.
