Used primarily as a coupling agent in silicone polymer synthesis, enhancing adhesion between organic and inorganic materials. It is especially effective in modifying surfaces of glass, metals, and minerals to improve compatibility with resin systems. Commonly applied in sealants, coatings, and adhesives where moisture resistance and durability are critical. Its vinyl group allows for crosslinking in curing processes, particularly in RTV (room temperature vulcanizing) silicones. Also utilized in the production of specialty silanes for electronic encapsulants and in composite materials to improve mechanical strength and thermal stability.
