The present invention relates to an aqueous dispersion as a concentrate for the activation stage of phosphating of metal surfaces, containing a dispersed particulate constituent and a thickener, the particulate constituent containing, in addition to dispersed inorganic compounds of polyvalent metal cations, polymeric organic compounds as dispersing agents which are composed at least partially of styrene and/or an α-olefin having no more than 5 carbon atoms and maleic acid, its anhydride and/or its imide, and which additionally comprise polyoxyalkylene units. The aqueous dispersion is further characterized by a D50 value above 10 μm. The present invention also relates to a method for anti-corrosion pretreatment of the surfaces of a metal material, in particular for zinc phosphating.

Aqueous dispersion for activating a metal surface and method for the phosphating thereof

The present invention relates to an aqueous coating composition comprising at least one aqueous dispersion or solution (A) of at least one electrophoretically depositable binder and optionally of at least one crosslinking agent, and also at least one aqueous sol-gel composition (B), for at least partly coating an electrically conductive substrate with an electrocoat material, where the aqueous sol-gel composition (B) is obtainable by reaction of at least one starting compound suitable for preparing the sol-gel composition (B) with water, with hydrolysis and condensation of the at least one starting compound, to a method for producing the coating composition, to the use thereof for at least partly coating an electrically conductive substrate with an electrocoat material, to a method for at least partly coating an electrically conductive substrate with an electrocoat material by at least partial electrophoretic deposition of the coating composition on the substrate surface, to an electrically conductive substrate at least partially coated therewith, and to an article or component produced from at least one such substrate.

Dip-coating composition for electroconductive substrates, comprising a sol-gel composition

The invention relates to a method for producing a pigment paste and an electrocoat containing the paste, the past being made by mixing solid pigment particles with a grind resin in the presence of water and/or an organic liquid, wherein the grind resin includes a dispersion of core-shell particles in an epoxide prepolymer which is liquid at 20&#xb0; C. and the core-shell particles have a silicone core and a polymer shell.

Method for producing a pigment paste, aqueous electrocoat material, use thereof, method for cataphoretic electrocoating, and coated article

The present invention relates to a method for producing an anticorrosion coating, wherein  The present invention relates, furthermore, to coated metallic substrates coated by the method of the invention. The present invention relates not least to the use of the anticorrosion primer for use in the method of the invention for improving the corrosion resistance of metallic substrates.
