Coating materials containing mixed oxide nanoparticles consisting of 50-99.9 by weight al203 and 0.1-50 by weight oxides of elements of main groups l or ll of the periodic table

摘要

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.
