Used as a surface modifier in coatings and adhesives to improve water repellency and adhesion to substrates. Enhances dispersion of fillers in composite materials by reducing particle agglomeration. Employed in sol-gel processes to produce hybrid organic-inorganic materials with improved flexibility and durability. Acts as a coupling agent in rubber and polymer formulations, promoting better filler-rubber interaction for enhanced mechanical properties. Also utilized in the formulation of water-resistant treatments for construction materials like concrete and masonry.
