Silicone resin--primer    The bonding force between the coating and the substrate includes mechanical bonding force, chemical bonding force, diffusion force and dipole force. The size of the binding force directly affects the adhesion of the coating.
The main methods to improve the adhesion between the coating and the substrate are: substrate grinding, sandblasting, reducing the construction viscosity of the coating, increasing the construction temperature, and improving the wettability of the substrate (wiping with solvent, corona, flame burning, oxidizing agent Treatment and other methods), related to silicone is the use of adhesion promoters, that is, the use of primers. The silicone materials used for primers are mainly silanes. 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 The material in the primer formulation.
