Abstract: Nanoparticles are claimed which consist of 50-99.99% by weight of alumina and 0.01-50% by weight of metal oxide of elements of main group I and II of the Periodic Table. These nanoparticles are obtained by drying a suspension of aluminum chlorohydrate, oxide formers and, if desired, crystallization nuclei, followed by calcining and comminution of the resultant agglomerates.

Abstract: The invention relates to coating materials containing silane-modified nanoparticles an organic binder and possibly additives, wherein the coating materials contain silane-modified nanoparticles which are obtainable by disaggregating agglomerates containing the particles in the presence of an organic solvent and simultaneous or afterwardly carrying out a silane treatment. Thus the silane-modified nanoparticles provide the coating materials and coatings with an improved scratch resistance.

Abstract: The invention relates to mixed oxide nanoparticles from aluminum oxide or oxides of the elements of the first and second main group of the periodic system. These mixed oxide nanoparticles are surface-modified with a coating agent, preferably a silane or siloxane.

Abstract: The invention relates to coating materials containing mixed oxide nanoparticles, an organic binder and possibly additives, wherein said coating materials contain the nanoparticles consisting of 50-99.9% by weight aluminium oxide and 0.1-50 % by weight oxide of elements of the I or II main group of the periodic system. The mixed oxide nanoparticles can also have a surface modified by another coating agent, preferably silane or siloxane. The inventive mixed oxide nanoparticles provide coating materials or to coatings with an improved scratch resistance.
