Used as a surface modifier in materials science to improve hydrophobicity and adhesion properties. Commonly applied in coatings and thin films to enhance water resistance and durability. Acts as a coupling agent between organic polymers and inorganic substrates, especially in composite materials. Frequently employed in the fabrication of self-assembled monolayers (SAMs) on silica or metal oxide surfaces for electronic and optical devices. Also utilized in the treatment of fillers and pigments to ensure better dispersion in non-polar matrices.
