Used as a surface modifier in coatings and adhesives to improve water repellency and adhesion on glass and metal surfaces. Commonly applied in the production of water-resistant treatments for construction materials like concrete and stone. Acts as a coupling agent in silicone polymers, enhancing compatibility between organic and inorganic components. Also utilized in the synthesis of specialty siloxane resins for release coatings and mold applications. Its hydrolytic stability makes it suitable for sealants exposed to moisture over time.
