摘要： The activating agent which is based on titanium(IV) phosphate and intended for use in the activation of metal surfaces before a zinc phosphating treatment contains one or more copper compounds and has a Ti:Cu weight ratio of 1:100 to 60:1 and optionally contains in addition at least one of the components consisting of condensed phosphate, silicate, complexing agent, water-soluble organic polymer, thickening agent, and surfactant. It is used to prepare aqueous activating baths for activating iron, steel, galvanized steel, zinc alloy-plated steel, aluminum-plated steel and aluminum before a zinc phosphating treatment, which baths contain 0.001 to 0.060 g/l Ti, 0.020 to 1.2 g/l orthophosphate (calculated as P.sub.2 O.sub.5), and 0.001 to 0.1 g/l Cu and so much alkali that the bath has a pH value of 7 to 11, preferably of 7.5 to 10.

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.

摘要： Disclosed is a zirconium-based metal pretreatment coating composition that includes a metal chelator that chelates copper in the metal pretreatment coating composition and thereby improves adhesion of paints to a metal substrate coated with the pretreatment coating composition and the chelating agent is present in a sufficient amount to ensure that in the deposited pretreatment coating on the metal substrate the average total atomic % of copper to atomic % of zirconium is equal to or less than 1.1. The pretreatment coating composition is useful for treating a variety of metal substrates.
