Used as a coupling agent in silica-based materials to enhance adhesion between organic and inorganic phases. Commonly applied in coatings, sealants, and composite materials where improved durability and stability are required. Provides excellent bonding in aqueous environments due to its hydrophilic trisodium salt groups. Frequently utilized in biomedical applications for surface functionalization of glass or silicon substrates, enabling immobilization of biomolecules such as enzymes or DNA. Also effective in corrosion inhibition by forming stable protective layers on metal surfaces. Its multifunctional structure supports chelation and dispersion in water-based systems, making it suitable for use in detergents and water treatment formulations.
