Used as a surface modifier 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 inorganic substrates and organic polymers. Serves as a coupling agent in composites, increasing durability and mechanical strength. Also utilized in the synthesis of specialty silicones for use in electronics and optical materials due to its ability to form stable, cross-linked networks.
