Used as a coupling agent in silicone-based formulations to improve adhesion between organic polymers and inorganic surfaces. Enhances water repellency and durability in coatings, sealants, and construction materials. Commonly applied in the production of weather-resistant architectural glazing, automotive sealants, and moisture-curable silicone systems. Provides excellent compatibility in hybrid organic-inorganic composites and is effective in improving dispersion and stability in fillers and pigments for paints and adhesives.
