The metal oxide nanoparticles include nano-sized zinc oxide, titanium oxide, iron oxide, zirconium oxide and cerium oxide, as well as mixed metal compounds, such as indium tin oxide, zirconium and titanium. For the color, paint and coating industry, these nanomaterials are of particular interest, as by the addition of nano-sized particles may be prepared paints, varnishes and coatings with special decorative and functional properties. Color and gloss characteristics are numbered among the decorative aspects; conductivity, microbial inactivation or antistatic properties are numbered to the functional aspects. By addition of nanoparticles, also the protective functions of paints and coatings, such as scratch resistance and UV stability can be improved. In the production of novel color and coating formulations, special nano-sized metal oxides, such as TiO2 and ZnO or alumina, ceria, silica, and nano-sized pigments, have been proven to be extremely promising components.
