PHOTOCATALYST COATING AND COATING FILM STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a photocatalyst coating which is hardly eroded even when a photocatalyst is excited and can properly adjust hydrophilicity of a coated surface. SOLUTION: The photocatalyst coating contains a hydrophilic resin wherein photocatalyst particles are dispersed, and a hydrophobic resin having compatibility to the hydrophilic resin. The hydrophilic resin is a tetrafluoro-ethylene-based resin obtained by graft polymerization of a sulfonic acid and/or a hydrolyzable siloxane resin. COPYRIGHT: (C)2010,JPO&INPIT
