摘要： The invention relates to a method for the currentless coating of substrates, comprising the steps of: I. providing a substrate, II. Optionally cleaning the substrate, III. applying an activation layer consisting of polyelectrolyte and/or salt with a first aqueous composition (= activation agent), IV. optionally intermediately drying the activation layer, V. rinsing the activation layer, wherein the activation layer is not removed completely, VI. contacting and coating the activated surfaces remaining after the rinsing with an aqueous composition in the form of a solution, emulsion and/or suspension to form an organic subsequent layer (= precipitation layer), VII. optionally rinsing the subsequent layer, and VIII. drying, wherein the activation layer is formed with an aqueous activation agent in the form of a solution, emulsion and/or suspension, which contains at least one cationic polyelectrolyte and/or at least one cationically active salt dissolved in water, wherein the aqueous composition for forming the subsequent layer has components which can be precipitated, condensed and/or salted out, are stabilised anionically, zwitterionically, sterically and/or cationically, and do not affect anionically and cationically stabilised components, and wherein the dry film formed thereby and consisting of the activation layer and the subsequent layer has a thickness of at least 1 µm.

摘要： The invention relates a method for the electroless coating of surfaces of articles or/and particles with a multiplicity of inorganic or/and organic water-insoluble particles to form a substantially flush-resistant layer of high particle density, in which the particles are applied to the surfaces to be coated in an aqueous composition that can be stabilized or is stable, in the form of a dispersion, and are applied to the surfaces to be coated substantially or predominantly by electrostatic forces and are applied to and secured on the surfaces to be coated substantially or predominantly by electrostatic forces, in which the surfaces to be coated are first activated by an activating agent, wherein an activation layer with charges is formed by the activating agent on the surfaces to be coated, these charges being of a charge that is opposite to the charges of the particles of the composition that are subsequently to be applied, or/and are oppositely charged, in which the particles applied in a coating step with a particle-containing composition are of a charge that is opposite to the charges of the activation layer, or/and are oppositely charged, wherein, in a or in each coating step with a particle-containing composition, a layer of an average thickness of approximately one or more average particle sizes of the particles applied is formed in each case on the surfaces to be coated and, optionally, the or each particle layer is subsequently formed into a film or crosslinked, whereby a layer thickness of the or each particle layer of the particles not formed into a film and/or of the coating(s) formed into a film or crosslinked that are produced therefrom that is in each case in the range from 5µm to 50µm is achieved.
