aochengchem: Silanes as adhesion promoters

Due to silane special structure and compose, has been successfully used to adhesion promoters, surface treatment agent for decades. Now silane have become the indispensable constituent of coatings and ink system .

When the coating contains a small amount of a silane coupling solvent, after which the coating of silane with the substrate migrate into the interface of the coating, the water reacts with the inorganic surface, the hydrolysis of a silanol group, and then form a hydrogen bond with the substrate surface hydroxyl groups or condensed -Si-M (M is an inorganic surface), while the silanol group of the silane molecules condensed with each other again, the membrane covering the mesh structure is formed on the substrate surface oligomerization. Even under flooding conditions, the silane coupling agent-modified substrate surface coatings of various inorganic good adhesions. Paint in the boundary layer between the base and the substrate, silane-based interaction with the paint, and varnish formation of silane-based mutual penetration of the network structure, and enhance the stability of their cohesion and water erosion, and stress in order by modulus the low modulus of the substrate to transfer the paint base, in order to significantly improve the adhesion to the substrate.
