摘要： In a process wherein a resinous coating is formed on a metallic surface by immersing the surface in an acidic aqueous coating composition containing dispersed particles of resin, wherein said composition forms on said surface a resinous coating which increases in thickness the longer the surface is immersed in the composition and wherein the resinous coating is contacted with an aqueous solution containing Cr in order to improve properties (e.g. corrosion resistance), the surface slip of the applied coating is increased by having dispersed in the Cr-containing solution a polymer which has a lower coefficient of friction than the applied resinous coating.
