Abstract
Acidic aqueous coating compositions containing an organic coating-forming material form coatings on metallic surfaces which are immersed therein. The thickness or weight of the coating formed by the coating composition is a function of the time the metallic surface is immersed in the composition. The resulting coatings have adhesion properties thereby providing an adherent base to which other coatings, for example, paint primers and/or final finish paints can be applied.
