It belongs to a new type of disilane, that is, there are two silane structures in the same molecular structure. There are six alkoxy groups on one molecule which can be hydrolyzed. It is double of the ordinary silane coupling agent. It can symmetrically combine with the hydroxyl groups on the surface of inorganic materials to form a regular and orderly surface structure. Therefore, it can form a higher crosslinking density on the surface of inorganic materials; at the same time, the silicone alcohol formed by hydrolysis of the product is more acidic than that formed by ordinary silane coupling agent, so it can form a stronger covalent bond with the hydroxyl groups on the surface of metal and inorganic materials, and it is not easy to hydrolyze.
It is an important raw material for the synthesis of fluorosilicone oil and fluorosilicone rubber.
It can not only endow general siloxanes with superior heat resistance, weather resistance, water sparing and demoulding properties, but also have the properties of water-proof, oil-resistant, solvent resistant and low surface tension of fluorine-containing compounds. It can be used in automobile, aircraft, aerospace, petrochemical, machinery and other important industrial sectors. The fluorosilicone material developed by this product can meet the requirements of severe working conditions, and the requirements of solvent resistance, fuel resistance, acid and alkali resistance are very high.
It can be used as a silane based coating on poly (PVDF) to synthesize a film for removing harmful volatile organic compounds. It can also be used to synthesize superhydrophobic carbon nanotube (CNT) hollow membrane for membrane desalination (MD) as environmental protection product of fresh water.
1H, 1H, 2h, 2h perfluorodecyltriethoxysilane is a fluorinated alkyl silane, which is mainly used to improve the wettability of the substrate by reducing the surface energy. It promotes the superhydrophobic coating by enriching the surface of CF 3 group and water contact angle higher than 150 °.
