Used as a surface modifying agent in the production of hydrophobic coatings and water-repellent films. It is particularly effective in treating glass, silica, and metal oxide surfaces to enhance moisture resistance. Commonly applied in the manufacturing of weather-resistant optical devices, anti-fogging coatings, and protective layers for electronic components. Its dual silane functionality allows for strong bonding to inorganic substrates while providing organic compatibility, making it suitable for hybrid material systems. Also utilized in specialty adhesives and sealants where improved adhesion and durability under humid conditions are required.
