As the core of the technology, silane is a kind of silicon-based organic/inorganic hybrid, whose chemical structure can be expressed as: Y-R-Si-X; Where X is the hydrolytic group, Y is the organic functional group that can react with the resin. Different silanes contain different X and Y groups and exhibit different rates of hydrolysis and reactivity. Because silane has this property, each specific field can be found to match the needs of the silane solution.
The hydrolyzed SiOH group forms hydrogen bond with the MeOH group on the metal surface, which is quickly adsorbed on the metal surface, and further dehydrates to form -Si-O-Me covalent bond (Me stands for metal). At the same time, the silane hydrolysate silanol molecules can condense and oligomerize with each other to form a Si-O-Si three-dimensional network film covering the surface of the metal substrate. While other silane molecules form organic films with Si-O-Si three-dimensional network structure on the metal surface through the condensation reaction between SiOH groups. This is the mechanism by which silane forms coatings on metal surfaces. After drying, the silane film formed on the surface of the metal substrate is combined with the electrophoresis paint or powder spraying through cross-linking reaction to form a firm chemical bond, so that good adhesion and stable film structure can be formed between the metal substrate, silane and paint through chemical bond.
