Abstract
Cleaned metal surfaces are coated with an aqueous anti-corrosion treatment. The anti-corrosion treatment includes an organofunctional silsesquioxane and a fluoro metallic acid such as HTiF, HZrF, as well as others and blends. The metal surface can be rinsed immediately after coating, making this anti-corrosion treatment suitable for preparing a metal surface for electrocoating.
