Abstract: Described herein is a coating composition including at least one graphene oxide including at least one monovalent metal ion selected from the group consisting of lithium, potassium and mixtures thereof (GO-M), at least one binder B and/or at least one silane compound SC, and at least one solvent S1. Also described herein is a process to produce the coating composition, a method to produce at least one coating layer on a substrate by using the coating composition and a coating layer or multilayer coating obtained by said method. Also described herein is a method of using graphene oxide including at least one monovalent metal ion selected from the group consisting of lithium, potassium and mixtures thereof in coating compositions to improve corrosion resistance of said coating compositions.

Abstract: Disclosed herein is a solvent-borne, two-pack coating composition. Further disclosed is a method of producing the coating composition, a method for coating and the coatings obtained therein, and the use of compounds (II) and (III) as corrosion inhibitors.

Abstract: Described herein is an aqueous coating composition (A) for at least partly coating an electrically conductive substrate with an electrocoat material, including (A1) at least one cathodically depositable resin binder, (A2) at least one crosslinking agent, (A3) at least 100 ppm of bismuth, based on the total weight of the coating composition (A), and (A4) lithium, in a form dissolved in (A), the lithium not exceeding a fraction of 300 ppm, based on the total weight of the coating composition (A). Also described herein are a method for producing (A), a coating method, and an at least partly coated substrate obtainable by the method.

Abstract: Described is a method for producing an anticorrosion coating, wherein (1) an anticorrosion primer comprising: (A) at least one organic resin as binder, and (B) at least one synthetic layered double hydroxide comprising organic anions, is applied directly to a metallic substrate; and (2) a polymer film is formed from the anticorrosion primer applied in stage (1), wherein the at least one synthetic layered double hydroxide (B) comprises at least one organic anion of an alpha-amino acid. Also described are coated metallic substrates coated by the method of the invention. Further described is the use of the anticorrosion primer in the method of the invention for improving the corrosion resistance of metallic substrates.
