Abstract: A combination of difunctional organic acid, preferably a hydroxy acid such as citric acid, or salt thereof with acrylic acid/acrylate polymers in zinc phosphate conversion coating forming liquid compositions, preferably also containing hydroxylamine, results in crystal size refinement in the coating formed and/or faster formation of a sufficiently thick conversion coating to protect against subsequent rusting of a ferrous substrate.

Abstract: Blemish and blister formation during autodeposition coating of non-ferrous metal surfaces, particularly galvanized steel and similar zinciferous surfaces, can be greatly reduced by exposing the surfaces to a blemish inhibiting aqueous solution of phosphonates, preferably from an aminophosphonic acid, before autodeposition coating.

Abstract: A composition for treatment and after treatment of surfaces, especially metals, with derivatives of polyphenol compounds is provided. The derivatives include substituted aminomethyl groups on at least some of the phenyl rings in the polyphenol polymers, with molecular weights within the range of about 700 to about 70,000 being preferred. The compositions are particularly useful for treating chromated aluminum surfaces prior to painting, to improve corrosion resistance, and when combined with surfactants, for treating plastic and painted surfaces to improve rinsability without water breaks.

Abstract: Chromated aluminum and aluminum alloy surfaces, to improve their corrosion resistance, are treated with composition for treatment and after treatment of surfaces, especially metals, with derivatives of polyphenol compounds that include substituted aminoethyl groups on at least some of the phenyl rings in the polyphenol polymers, with molecular weights within the range of about 700 to about 70,000 being preferred.

Abstract: An otherwise conventional solid Jernstedt salt composition for activating metal surfaces to improve the quality of subsequently deposited phosphate conversion coatings on the activated metal surface and which rapidly dissolves, utilizing in the composition a mixture of sodium and potassium salts, preferably condensed phosphate salts, in such amounts that the ratio of potassium to titanium is within the range from 8.0:1.0 to 40:1.0 and the ratio of potassium to sodium is within the range from 0.9:1.0 to about 2.5:1.0.
