Abstract
A super water-repellent coating film is formed of a super water-repellent coating material comprising an organic coating material composed of organic polymer, a filler mixture composed of plural kinds of fillers of at least 5 nm in average particle diameter, which is dispersed in the coating material, and a perfluoropolyoxyalkyl group compound. Because the surface of various solid bodies can be made super water-repellent by a simple process using this water-repellent coating material, the coating film can be utilized in various fields, such as preventing snow covering, frosting, ice coating, water adhering, and other applications.
