摘要
(IN201647029678) The invention relates to a method for coating metallic surfaces of substrates with surfaces of aqueous compositions, hereinafter also referred to as coating compositions, in the form of a dispersion and/or a suspension containing at least one stabilized binder and a gelling agent and with the cations dissolved out of the metallic surface in a pretreatment stage and/or during the contacting, and the invention relates to such a coating based on an ionogenic gel, in which the coating is formed by: I.  Providing a substrate with a cleaned metallic surface, II.  Contacting and coating the metallic surface with a first aqueous composition in the form of a dispersion or suspension, III.  Optionally rinsing the organic coating, IV.  Optionally drying the organic coating and V.  Coating with at least one additional coating composition before drying and cross linking all applied layers, wherein the stabilized binder must fulfill the following conditions: a) an aqueous mixture of deionized water, 0.2% to 2% by weight of the gelling agent and 5% to 20% by weight of the stabilized binder b) is adjusted to a pH of 1 to 7; c) a cleaned substrate is immersed in the mixture according to b) for at least 1 minute at room temperature and d) a check is performed on whether an organic coating of at least 1 pm has been deposited, wherein e) an additional test without a gelling agent is performed by preparing a mixture of deionized water and 5% to 20% by weight of the dispersion to be tested; f) the mixture prepared under e) is also adjusted to a pH of 1 to 7 and g) the test described under c) and d) is repeated.
