Used as a coupling agent in the production of silicone polymers, enhancing adhesion between organic and inorganic materials. Applied in surface treatment of glass, metals, and fillers to improve compatibility with resins and coatings. Also employed in the synthesis of modified silanes for use in sealants, adhesives, and rubber compounds. Its reactive chloropropyl group allows for further functionalization in organic synthesis. Commonly utilized in the manufacturing of fiberglass for reinforcement in composite materials. Plays a role in creating hydrophobic surfaces in various industrial applications.
