Alkoxysilanes (mainly various silane coupling agents) as adhesion promoters must be used at the interface between the coating and the substrate or the interface between the sealant and the adhesive material to increase adhesion. When using an adhesion promoter as a primer, the silane is usually formulated into a 0.5% to 5% diluent of ethanol or alcohol and then applied to the surface of the substrate by coating or spraying. In addition to using silane primers to improve viscosity, it can also improve hydrophobicity, UV resistance, weather resistance, thermal stability, surface activity, chemical resistance, and corrosion resistance. Select adhesion promoter to match the organic molecules in the coating

The bonding force between the coating and the substrate includes mechanical bonding force, chemical bonding force, diffusion force, and dipole force. The amount of binding force directly affects the adhesion of the coating.

The main methods to improve the adhesion between the coating and the substrate are: sanding the substrate, sandblasting, reducing the construction viscosity of the coating, increasing the construction temperature, and improving the wettability of the substrate (using solvent wipe, corona, flame burning, oxidant Methods such as treatment), related to silicone is the use of adhesion promoters, that is, the use of a primer, the silicone material used for the primer is mainly silane. Alkoxysilane can improve the adhesion, fluidity, leveling, abrasion resistance, pigment and filler dispersion, water resistance and salt spray resistance of coatings and substrates. It has been widely used in various metals and silicon-containing materials. Material in the primer formulation.
