Used as a surface treatment agent to modify the properties of inorganic materials such as glass, silica, and fillers in composite materials. It enhances adhesion between organic polymers and inorganic substrates by acting as a coupling agent. Commonly applied in sealants, adhesives, and coatings to improve water repellency and durability. Also utilized in the production of silicone resins and as an intermediate in the synthesis of other silane derivatives for industrial applications. Its reactivity with moisture makes it effective for creating hydrophobic surfaces in construction and automotive materials.
