Trifluorofluorooctyltriethoxysilane releases low-molecular-weight alcohols after hydrolysis. The resulting active silanol can chemically bond with hydroxyl, carboxyl, and oxygen-containing groups in many inorganic and organic substrates. A self-assembled monomolecular fluorosilicon film layer is formed on the surface of the inorganic substance. Application of trifluorofluorooctyl triethoxysilane as an organic silane compound, the surface of the glass is hydrophobic and antifouling, anti-ultraviolet coating; the surface of metal (copper, iron, aluminum, etc.) is anti-oxidation; the surface of ceramic and marble is waterproof and Pollution; waterproof and anti-fouling and anti-corrosion treatment of wood and products; natural fiber (wool, cotton, leather, etc.) products to reduce water holding capacity and improve surface water repellency and anti-fouling finishing; waterproof and anti-fouling and weathering of cultural relics and masonry Protection treatment, etc.
