Used primarily as a coupling agent in the production of silicone polymers, it enhances adhesion between organic and inorganic materials. It is widely applied in surface treatment of glass fibers to improve their compatibility with resin matrices in composite materials. Additionally, it serves as an intermediate in the synthesis of various organosilicon compounds, which are essential in coatings, sealants, and adhesives. Its ability to modify surfaces makes it valuable in creating water-repellent coatings and improving the durability of materials in harsh environments.
