METHOD FOR THE PRODUCTION OF COATINGS, ADHESIVE LAYERS OR SEALS FOR PRIMED OR UNPRIMED SUBSTRATES

摘要

The invention concerns a method for the production of coatings, adhesive layers or seals for primed or unprimed substrates, wherein (1) at least one coating material that can be hardened thermally and/or with actinic radiation and/or an adhesive and/or at least one sealant that can be hardened thermally and/or with actinic radiation in the form of a powder slurry is applied on and/or to the primed or unprimed substrate; (2) the resulting powder slurry layer is dried; (3) the resulting solid layer (2) is molten by heating and (4) the resulting molten layer obtained in step (3) of the method is hardened with near infrared radiation (NIR) in its molten state during and/or after solidification.
