1. Bisilane coupling agent, which has two silane structures in the same molecular structure, with six alkoxy groups on one molecule, can form higher crosslinking density on the surface of inorganic materials; The silanol formed by hydrolysis of this product is more acidic than the silanol formed by ordinary silane coupling agents, so it can form stronger covalent bonds with the hydroxyl groups on the surface of metal and inorganic materials, and is not easily hydrolyzed. 2. Environmentally friendly phosphorus and heavy metal free surface treatment solution, replacing traditional phosphating and passivation processes. 3. The crosslinking agent in adhesives and sealants provides moisture curing function and improves the adhesion to the substrate. 4. Combining with coupling agents can greatly improve the adhesion and water resistance of silane coupling agents.
