    摘要： The invention relates to a process for treating metal surfaces, preferably of aluminum, aluminum alloys and steel, for the subsequent application of organic coating compositions. The metal surfaces are wetted with an aqueous bath solution containing chromium(III)ions, fluoride ions and an organic film former which is soluble or homogeneously dispersible in water, after which the solution applied is dried and converted by heating into a water-insoluble film.The bath solution preferably contains the following constituents and approximate quantities thereof: 0.5 to 10 g/l of chromium(III)ions, 0.55 to 11 g/l of fluoride ions, 0.6 to 12.5 g/l of phosphate ions, and 0.15 to 5.0 g/l of organic film former. The organic film former preferably used is a polymer containing free carboxyl groups, more preferably a homopolymer and/or copolymer of acrylic and/or methacrylic acid.

    摘要： Improved autodeposited coatings on metallic surfaces are formed by contacting the metallic surfaces with an autodepositing composition comprising an acidic aqueous coating solution containing dispersed solid resin particles or either an internally stabilized or externally stabilized vinylidene chloride polymer, an exemplary internally stabilized polymer being prepared from vinylidene chloride and a monomeric surfactant which includes an inorganic ionizable group, and an exemplary externally stabilized polymer being prepared from vinylidene chloride and a reactive comonomer, the resulting resin particles having surfactant adsorbed thereon, said autodeposited coatings having extremely good corrosion resistant properties without treatment with a reaction rinse such as a chromium rinse.

    摘要： The adhesion of, and corrosion protection provided by, organic surface coatings to underlying metal can be significantly improved if the degreased, etched, and pickled metal surfaces to be coated are first treated with an aqueous solution and/or dispersion of aluminum-zirconium complexes, which are obtainable as the reaction-product of a chelated aluminum component, an organo-functional ligand component, and a zirconium oxyhalide component, with the organo-functional ligand being chemically bonded to the chelated aluminum unit and the zirconium unit in the complex, and are subsequently treated with dilute aqueous solutions, emulsions, and/or dispersions of one or more inorganic and/or organic film-forming materials prior to coating the surfaces with conventional organic surface coatings.
