Lacquers & Coatings

Application	Base material	Examples
Transparent improvement of scratch resistance in various coating systems (2K-PU, epoxy, acrylate)	n-SiO₂ n-Al₂O₃ n-ZrO₂	Scratch-proof automotive topcoats Scratch-proof parquet lacquers Scratch-proof furniture lacquers Scratch-proof lacquers for electronic devices
Transparent and sustainable mineral UV absorption	n-TiO₂ n-ZnO (n-Fe_xO_y)	UV durable wood varnishes for exterior applications; with n-ZnO and n-Fe_xO_y UV absorbing transparent topcoats
Controlled adjustment of translucence and transparence	n-SiO₂ n-Al₂O₃ n-TiO₂	Use as matting agent for lacquers and coatings
Transparent functionalization of surfaces	n-TiO₂ n-SiO₂ n-ZnO	Photocatalytical coatings (so called self-cleaning effect coatings); with n-TiO₂ only Easy-to-clean coatings, e.g., via lotus effect or fluorocarbon-functionalized particles; with n-SiO₂ only Fungicidal coatings; not possible with TiO₂ and SiO₂
