ABSTRACT:
A process for providing a priming layer of aluminum hydroxyoxide on aluminum and aluminum alloy surfaces comprising treating the surface with a chemical reagent having a solvent action for the naturally-occurring oxides which form on such surfaces until said oxides are dissolved, and contacting said surfaces with steam while a film of the reagent is still present on the metal surface. The priming layer provides for excellent adhesion of subsequent organic coatings to the metal surface.
