Used as a surface treatment agent in the production of mineral-filled composites and glass fiber-reinforced plastics. Enhances adhesion between organic resins and inorganic materials by acting as a coupling agent. Particularly effective in improving dispersion and moisture resistance in silicone rubber and sealant formulations. Also applied in specialty coatings where hydrophobicity and chemical stability are required. Its branched alkyl structure contributes to lower volatility and improved hydrolytic stability compared to simpler alkoxysilanes, making it suitable for high-performance applications under humid conditions.
