Used primarily as an intermediate in the production of silicone polymers and resins. It serves as a key coupling agent in surface treatment of mineral fillers, enhancing adhesion between organic polymers and inorganic materials in composites. Commonly applied in sealants, adhesives, and coatings to improve water repellency and durability. Also utilized in the synthesis of silane coupling agents that modify glass fibers and pigments for better dispersion and stability in polymer matrices. Its reactivity makes it valuable in vapor deposition processes for creating protective silica-based films on electronic components.
