Adhesive primers based on polyvinyl acetals dissolved in organic solvents as well as pigments, acidic phosphorus compounds, synthetic resins and possibly other conventional additives, which are derivatives of epoxy resins as synthetic resins. whose epoxy groups are largely implemented. These paints impart excellent corrosion resistance to the metal surfaces treated with them, do not penetrate through the top coat and can be produced and used without the use of chromate pigments. |
