摘要： This invention relates to a method and compositions for coating aluminum in order to improve both corrosion resistance and paint adhesion. By using a coating composition consisting essentially of (a) polyacrylic acid or esters thereof and (b) at least one acid selected from the group consisting of H.sub.2 ZrF.sub.6, H.sub.2 TiF.sub.6, and H.sub.2 SiF.sub.6, the characteristics of the treated aluminum surfaces are improved, while process waste disposal problems associated with conventional chrome/phosphate coating are avoided.

摘要： Lubricating oils and aluminum fines are removed from aluminum surfaces by contacting the surfaces with an aqueous solution containing sulfuric acid, hydrofluoric acid, and an alkali metal 2-butoxyethoxyacetate anionic surfactant. The solution may also contain one or more low foaming nonionic surfactants.

摘要： Heating an aqueous mixture of a fluoroacid such as H.sub.2 TiF.sub.6 and an oxide, hydroxide, and/or carbonate such as silica produces a clear mixture with long term stability against settling of any solid phase, even when the oxide, hydroxide, or carbonate phase before heating was a dispersed solid with sufficiently large particles to scatter light and make the mixture before heating cloudy. The clear mixture produced by heating can either be mixed with water soluble and/or water dispersible polymers, for example with dispersed polymers of the diglycidyl ether of bisphenol-A or an acrylic acid polymer, 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. Another composition that improves the corrosion resistance of metals after contact with them is an aqueous solution of a mixture of: (A') a water soluble or dispersible polymer having at least one --OH group per polymer molecule selected from the group consisting of polyvinyl alcohol, polyethylene glycol, modified starch, and mixtures thereof, and (B') polymers and copolymers of acrylic and methacrylic acid and their salts.
