Abstract: A method of removing a coating made of an organic material, in particular an organic lacquer or a polymer coating, which adheres to the surface of tin-plated sheet steel. In a first step, the tin layer of the tin-plated sheet steel is completely or incipiently melted by exposure to electromagnetic radiation with a predefined wavelength, to which the organic coating is at least primarily transparent, with the organic coating becoming detached from tin layer, and in a second step, the organic material of the coating which detached from the tin layer is removed.

Abstract: A method for the coating of a chromium-free surface of a tin-plated steel sheet with a polymer coating, with the chromium-free tin surface of the tin-plated steel sheet first electrochemically oxidized in a first step and a polymer coating applied on the oxidized tin surface in a second step, and an apparatus for the carrying out of the method. A tinplate coated with a polymer coating made of polyethylene terephathalate (PET) and passivated chromium-free, wherein only one thin tin oxide layer and perhaps an adhesion promoter layer are present between the tin surface of the tinplate and the polymer coating, and the use of such a tinplate for the production of packagings.

Abstract: A method for coating a steel sheet with a metal layer includes the following steps: application of a first thin metal layer as a flash coating; melting the metal layer from the flash coating; and application of at least one additional metal layer onto the metal layer from the flash coating. To increase the corrosion resistance of the coated steel sheet and to improve the energy and resource efficiency of the coating method, with which a steel sheet having a high corrosion resistance and good weldability and with a good deep drawing and ironing behavior is to be produced, the thickness of the metal layer from the flash coating is at most 200 mg/m2 and the metal layer from the flash coating is melted with electromagnetic radiation of high energy density.
