Method for producing radiation-hardenable coating formulations and use thereof for the production of scratch-resistant, abrasionproof and adhesive coatings

摘要

The invention relates to a cost-effective method that can be carried out in a simple manner for the production of radiation-hardenable coating formulations. Said method is characterized in that at least one multifunctional acrylate monomer or oligomer (component I) is made to react with an amino alkoxysilane having two or three hydrolyzable radicals and one or two non-hydrolyzable radicals (component II) under conditions of the Michael addition, the resulting Michael adduct is reacted with the anhydride of an unsaturated dicarboxylic acid (component III). The alkoxy groups of the reaction product are hydrolyzed and nanoscale oxides or mixtures of nanoscale or microscale oxides of metals or semimetals or the mixed oxides thereof (component V) are added in powder form. A photoinitiator is optionally added once the reaction is finished. The invention also relates to the use of the coating formulations produced according to said method in the production of scratch-resistant, abrasionproof and adhesive coatings.
