Used as a coupling agent in silicone polymer synthesis, enhancing adhesion between organic and inorganic materials. Commonly applied in sealants, coatings, and encapsulation systems where moisture resistance and thermal stability are required. Also serves as a precursor in the production of functionalized siloxane materials for specialty adhesives and surface treatments. Its vinyl group enables crosslinking in cure systems, particularly in addition-cure silicones used in electronics and medical devices.
