The invention relates to a liquid coating substance which is essentially or completely devoid of corrosion-inhibiting pigments, which can be hardener by actinic radiation, and organic solvents.Said coating substance contains, (A) at least one component selected from the groups comprising low molecular, oligomer and polymer organic compounds which contain at least one group which can be activated by actinic radiation, in addition to air and oxidatively dried alkyd resins, (B) at least one component selected from the groups comprising acidic esters of polyphosphorous acids and monophosphorous acids having at least one compound (b1) containing at least one hydroxyl group and at least one group which can be activated by actinic radiation, and (C) at least one type of nanoparticle. The invention also relates to method for the production and use thereof.
L'invention concerne un matériau de revêtement liquide durcissable par rayonnement actinique, essentiellement ou entièrement libre de pigments anticorrosion et de solvants organiques, contenant (A) au moins un composant choisi dans le groupe des composés organiques oligomères et polymères de faible poids moléculaire, contenant au moins un groupe activable par rayonnement actinique, ainsi que des résines alkyde séchant à l'air et de façon oxydative; (B) au moins un composant choisi dans le groupe des esters acides d'acide polyphosphorique et d'acide monophosphorique comportant au moins un composé (b1) contenant au moins un groupe hydroxyl et au moins un groupe activable par rayonnement actinique; et (C) au moins un type de nanoparticules. L'invention concerne également des procédés de fabrication dudit matériau de revêtement.
