Abstract

Heating an aqueous mixture of a fluoroacid such as H2TiF6 and an oxide, hydroxide, and/or carbonate such as silica produces a clear mixture with long term stability against settling of any solid phase. The clear mixture produced by heating can either be mixed with water soluble and/or water dispersible polymers that are polyhydroxyalkylamino-substituted polymers and/or copolymers of p-vinylphenol, or with soluble hexavalent and/or trivalent chromium, to produce a composition that improves the corrosion resistance of metals treated with the composition, especially after subsequent painting.
