Used as a surface modifying agent in the production of silica-based materials, enhancing hydrophobicity and improving compatibility with organic matrices. Commonly applied in coatings, sealants, and adhesives to promote adhesion between organic polymers and inorganic surfaces. Also serves as a coupling agent in composite materials, increasing durability and mechanical strength. Frequently utilized in the synthesis of specialty siloxane polymers and as a reagent in organic synthesis for introducing silyl groups.
