The main role of the primer layer is to prevent corrosion reaction or to change reaction path on the metal surface to form a stable corrosion‐resistant surface. For example, zinc content is very important for the CP of the steel substrates in zinc‐rich primers. It is also essential that the primers have good adhesion to the metallic substrate and to the middle layer.
