Used as a coupling agent in silicone polymer synthesis, enhancing adhesion between organic and inorganic materials. Commonly applied in the production of water-repellent coatings for glass, ceramics, and metals. Also serves as an intermediate in the manufacture of silane-based primers and sealants, improving durability and moisture resistance in construction and automotive applications. Its reactivity with hydroxyl groups makes it effective in surface modification of fillers for silicone rubber, promoting better dispersion and mechanical properties.
