METHOD FOR PRODUCING COATINGS FROM COATING MATERIALS, WHICH CAN BE CURED THERMALLY AND BY USING ACTINIC RADIATION

摘要

The invention relates to a method for producing coatings from coating materials, which can be cured thermally and by using actinic radiation, on primed or non-primed substrates by: (1) applying at least one coating material, which can be cured thermally and by using actinic radiation, to a primed or non-primed substrate, whereby producing a layer that is comprised of the coating material, and; (2) curing the layer by using heat and actinic radiation. The inventive method is characterized in that a coating material is used that consists of:(A) compounds, which, with a statistical mean, contain at least one free isocyanate group and at least one bond per molecule that can be activated by means of actinic radiation; (B) (meth)acrylate copolymerizates that contain hydroxyl groups, and optionally of; C) additives selected from the group comprised of pigments, fillers, nanoparticles, bonding agents, reactive diluents, cross-linking agents for thermal curing, solvents, water, UV absorbers, light stabilizers, radical scavengers, initiators, catalysts for thermal cross-linking, degassing agents, slip additives, polymerization inhibitors, defoaming agents, emulsifiers, wetting and dispersing agents, adhesion promoters, flow-controlling agents, film-forming auxiliary agents, sag control agents (SCA), rheology controlling additives (thickeners), flame proofing agents, siccatives, drying agents, skinning inhibitors, corrosion inhibitors, waxes and delustering agents.
