Used as a silylating agent in organic synthesis, particularly for introducing hydrophobic groups into molecules. Commonly applied in the production of silicone polymers and resins, where it acts as a coupling agent to improve compatibility between organic and inorganic materials. Frequently employed in surface modification of fillers, glass fibers, and minerals to enhance dispersion and mechanical properties in composites. Also utilized in the manufacture of adhesives, sealants, and coatings to improve water resistance and adhesion to substrates.
