1H,1H,2H,2H-Perfluorooctyltrimethoxysilane (TMFOS) is an organosilicon compound utilized as a coupling agent to enhance the bond strength between fluorine-containing resin and substrates. It finds application in the preparation of waterproof, oil-proof, and anti-fouling treatment agents. 1H,1H,2H,2H-Perfluorooctyltrimethoxysilane is also employed as a finishing agent to reduce the water absorption capacity of natural fiber products (such as wool, cotton, and leather), while improving surface water repellency and stain resistance. Additionally, it serves as a water-repellent and antifouling treatment for glass surfaces.
