Abstract: A metal sheet, inclusive of a metal strip, having a front side and a back side, both the front side and the back side comprising a first coating having an average thickness in the range from 0.5 to 10 μm, wherein the first coating of the front side contains particles, which release divalent or multivalent metal ions upon the action of an acid, in such an amount that a self-depositing coating agent forms, upon contact with the front side, a second coating thereon, whereas this is not the case for the first coating of the back side. The first coating of the front side can be overcoated with a self-depositing coating agent. Cut edges that do not have a first coating can be covered with the self-depositing coating agent. Correspondingly coated metal sheets, as well as a method for the manufacture thereof, are furthermore within the scope of the invention.

Abstract: The invention provides high solids epoxy-based autodeposition coating materials that have improved moisture barrier properties and/or anti-corrosive properties and a means to obtain the high solids epoxy-based autodeposition coating materials that eliminates/minimizes the need for process solvents. A hydrophobic water barrier enhancing agent, epoxy pre-polymer and ethylenically unsaturated monomer, as an alternative to organic solvent, are combined to yield an epoxy pre-polymer-monomer-hydrophobic water barrier enhancing agent blend, which may be blended with other coating components and additives. The resulting blend is then dispersed in water with surfactant and the ethylenically unsaturated monomer is polymerized (in the presence of other formulation components) to yield a dispersion. The dispersion may then be used as one component of a coating formulation. The coating formulation can then be applied to materials and cured to form a final coating.

Abstract: A method for applying at least one coating composition to an electrochemically active metal substrate, and the coated substrate produced thereby are disclosed. Preferably, an articulable electromechanical device such as a robot arm is utilized to aid in precision coating electrochemically active metal substrates, particularly complex shaped electrochemically active metal substrates through autodeposition. The electromechanical device is articulable through a wide range of motions and can substantially eliminate drip edges or pockets of retained coating in otherwise poorly draining areas of the substrate, producing fully and/or evenly coated, aesthetically pleasing coated substrates. Throughput of coated substrates is maximized through the method of the present invention.

Abstract: A multilayered coating (10) that is applied to a metal substrate (12). The coating comprises a protective zone of an insoluble crystalline phosphate formed by reaction of the substrate (12) with zinc phosphate. A film (16) of a polymer resin is deposited on the insoluble crystalline phosphate zone (14). In one embodiment, the multilayered coating (10) includes a coat of paint (18) that is applied to the polymer resin (16). A process for applying the multilayered coating to the metal substrate includes the steps of: applying a zinc phosphating solution to at least a portion of the substrate, which converts the surface to a zone of an insoluble crystalline phosphate; rinsing the zone; and autodepositing a film of a polymer resin thereupon.

Abstract: A composition and method is described for providing conformal protective or decorative polymer coatings on metals such as aluminum, copper, iron, steel, zinc, and their formation by dip autopolymerization. In accordance with the present invention, an acidic solution of organic monomer undergoes autopolymerization upon contact with a metal substrate, thereby forming a polymeric coating on the substrate. The method comprises providing the acidic monomer solution, dipping the metal substrate to be coated for a prescribed period of time depending on the thickness of the coating desired, and then removing the substrate from the solution. Importantly, the polymerization requires no application of external driving force, such as thermal or electrical energy. The coatings thus formed are up to 50 microns thick, and conform to the shape of the substrate. These coatings further have uniform thickness, and excellent thermal stability and protective properties. In one preferred embodiment of the present invention, the composition comprises an acidic solution of an organic electron acceptor monomer that undergoes autopolymerization in contact with a metal substrate, thereby forming a polymeric coating on the substrate. In another preferred embodiment of the present invention, the composition comprises an acidic solution of an organic electron acceptor monomer and an organic electron donor monomer that undergo autopolymerization in contact with a metal substrate, thereby forming a polymeric coating on the substrate. Metal-polymer composites are also described.
