The invention relates to a method for producing coatings, adhesive layers or sealing systems for primed or unprimed substrates. The inventive method comprises the following steps: applying to and/or introducing into the substrate (1) coating substances, adhesive substances and/or sealing compounds that contain a component (A) which comprises in the statistical average at least one group (a) with at least one bond per molecule that can be activated by actinic radiation in the form of (1.1) a water-free and solvent-free liquid or melt, (1.2) a powder, (1.3) a dispersion or a solution in at least one organic solvent, or (1.4) in an aqueous medium, (2) drying the layer from a dispersion or solution (1.3) or (1.4) or allowing the resulting layer of the melt (1.1) to solidify or maintaining it in the molten state by heating, (3) melting the solid layer (1.2), (1.3) or (1.4) by heating, and (4) curing the liquid layer resulting from process step (1) or the molten layer resulting from process step (2) or (3) in the molten state, during solidification and/or after solidification with radiation in the near infrared range. |
