METHOD OF COATING METAL SURFACES OF SUBSTRATES AND OBJECTS COATED IN ACCORDANCE WITH SAID METHOD Russian patent published in 2018 - IPC C09D5/08 B05D7/14 B05D7/16 B05D1/18 

FIELD: technological processes.

SUBSTANCE: invention relates to a method of coating surfaces, as well as the corresponding coating and use of products coated with this method. Method of coating metal surfaces of substrates, comprising or consisting of the following steps: I. providing a substrate having a cleaned metal surface, II. contacting and coating metal surfaces with an aqueous composition in the form of a dispersion and/or suspension, IV. drying and/or baking the organic coating, or V. coating with a coating composition of the same type or a further coating composition before a drying and/or baking, wherein II includes coating using an aqueous composition in the form of a dispersion or/and suspension containing from 2.5 to 45 wt% of at least one non-ionically stabilised binder and from 0.1 to 2.0 wt% of a gelling agent, wherein the aqueous composition has a pH in the range from 0.5 to 7, and also forms, with cations leached from the metal surface at step I or/and during contacting at step II, a coating based on ionic gel, and non-ionically stabilised binder is a dispersion of film-forming polymers containing organic particles based on polyacrylates, polyurethanes, polyepoxides and/or hybrids thereof and wherein the gelling agent is at least one anionic polysaccharide with a degree of esterification and/or amidation of carboxyl functional groups in the range from 1 to 75 % based on the total number of alcohol and carboxyl groups.

EFFECT: method of coating metal surfaces of substrates and articles coated with this method are disclosed.
