Abstract: A method for electroless coating of substrates by applying an activating coat of polyelectrolyte or salt with a first aqueous composition; rinsing the activating coat such that the activating coat not being entirely removed; contacting and coating of the activated surfaces that have remained after rinsing with an aqueous composition in the form of a solution, emulsion or suspension, to form an organic secondary coat; and drying. The activating coat is a solution, emulsion or suspension containing a anionic polyelectrolyte or at least one anionic salt in solution in water. The aqueous composition forming the secondary coat has constituents which can be precipitated, deposited or salted out and which are anionically, zwitterionically, sterically or cationically stabilized. The dry film formed in the process, comprising the activating coat and the secondary coat, has a thickness of at least 1 ?m.

Abstract: A method for electroless coating of a substrate by applying an activating coat of polyelectrolyte or salt with a first aqueous composition, rinsing of the activating coat such that the activating coat is not entirely removed The activated surface that has remained after rinsing is then contacted with an aqueous composition in the form of a solution, emulsion or suspension to form an organic secondary coat (precipitation coat), and drying. The activating coat contains at least one cationic polyelectrolyte or at least one cationic salt in solution in water. The aqueous composition which forms the secondary coat contains constituents which can be precipitated, deposited and/or salted out and which are anionically, zwitterionically, sterically or cationically stabilized. The dry film formed in the process, which is made of the activating coat and the secondary coat, has a thickness of at least 1 ?m.

Abstract: A method for the electroless coating of surfaces of articles and particles with a multiplicity of inorganic 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 surface 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. 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.
