Used as a coupling agent in silicone-based formulations to improve adhesion between organic and inorganic materials. Enhances durability and water resistance in coatings, sealants, and adhesives. Commonly applied in construction and automotive industries where strong bonding to glass, metals, and ceramics is required. Also functions as a crosslinking agent in silicone polymers, improving thermal stability and mechanical strength. Its vinyl group allows for further chemical modification in polymerization processes, making it useful in specialty resins and hybrid materials.
