    摘要: The invention relates to an electrically conductive, weldable, anti-corrosion composition that is substantially devoid of solvents, for coating metal surfaces. Said composition contains the following, (in relation to the total composition): a) between 5 and 98 wt. % of an organic binding agent; b) between 0 and 15 wt. % of an anti-corrosion pigment, c) between 20 and 90 wt. % of a conductivity pigment with a density of at least 3 g/cm and/or between 2 and 20 wt. % of a conductivity pigment with a density of less than 3 g/cm . The viscosity of said composition permits it to be applied in a coil-coating method. Preferably, the percentage by weight of said conductivity pigment increases as the density of the pigment increases. The binding agent can be cured by the action of high-energy radiation and preferably contains the following components: aa) at least one polyester resin, urethane resin or epoxy-modified (meth)acrylate resin; ab) at least one reactive thinner; and ac) at least one photoinitiator. According to said method for applying this type of anti-corrosion composition, in a preliminary step, the metal surface is brought into contact with a liquid that contains at least one low-molecular organic compound with at least one group that can be cross-linked by a radical polymerisation and at least one H-active group. The invention also relates to correspondingly coated sheet metal and metal parts, which can be subsequently painted, and to a method for producing painted metal parts of this type.

    摘要: Disclosed is a method for coating metals, especially zinc and the alloys thereof. According to said method, the metal a) is subjected to a conversion treatment by contacting the same with a conversion solution containing at least one simple or complex salt of at least one metal M, and c) is contacted with a coating agent which contains c1) a total of 5 to 30 percent by weight of one or several aliphatic crosslinking baking urethane resins, c2) a total of 10 to 30 percent by weight of one or several crosslinking agents for component c1, and c3) 4 to 30 percent by weight of one or several anticorrosive pigments, and the coating obtained in partial step c) is hardened. The inventive method is preferably carried out as a continuous no-rinse process. The invention further relates to a metal sheet with a coating that is obtained according to the disclosed method, a shaped part made from such a metal sheet or an object that contains such a metal sheet or a shaped part therefrom, and the use of such a metal sheet, shaped part, or object in the exterior zone of buildings.
