Abstract

Coating system on metal surface by immersion in a dispersion of resin particles in acidic aqueous medium, the coating forming composition comprising a dispersion of solid particles of resin in an aqueous acid phase capable of attacking a metal surface immersed in it to generate from it metal ions that destabilize the dispersion adjacent to the metal surface, without the application of any external electrical load, causing deposition on the metal surface of a resinous coating that increases in weight or thickness over time, characterized in that the concentration of any surfactant present in the aqueous phase of the composition is below the critical micelle concentration.
