Used as a surface treatment agent in coatings and adhesives to improve water repellency and adhesion on inorganic surfaces. Commonly applied in the formulation of water-resistant films and as a coupling agent in silicone-based systems. Also utilized in specialty sol-gel processes where controlled hydrolysis and crosslinking are required. Its methoxy groups allow for milder reaction conditions compared to alkoxy silanes with longer chains, making it suitable for sensitive formulations.
