Used as a coupling agent in the production of composites and adhesives, enhancing the bond between organic and inorganic materials. Applied in surface treatment of glass, minerals, and fillers to improve hydrophobicity and adhesion properties. Commonly utilized in coatings and sealants to increase durability and resistance to moisture. Plays a role in the modification of silica-based materials for better dispersion in polymer matrices. Also employed in the preparation of hydrophobic surfaces for various industrial applications.
