It combines the excellent properties of organosilicon and organofluorine. In its molecule, it also has the reaction groups that can combine with inorganic materials (such as glass, silica sand, metal, etc.) and organic materials (such as synthetic resin, rubber, etc.), which can connect the two materials with different properties, improve the performance of composite materials and increase the bonding strength 。
It is an important monomer for the synthesis of fluorosilicone rubber, fluorosilicone oil and other fluorosilicone products. Fluorosilicone products have excellent oil resistance, solvent resistance, chemical resistance and good high and low temperature resistance, and have important applications in the fields of automobile, aviation, machinery, petrochemical and military.
It is not only an important coupling agent of fluorosilicone, but also an important raw material for the preparation of fluorosilicone rubber and fluorosilicone resin.
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.
