Abstract
The present invention provides an antifouling coating formed from a water-based coating composition comprising 0.1% by mass to 10% by mass of ultrafine silica particles having an average particle size equal to or less than 25 nm, 5% by mass to 50% by mass, relative to the ultrafine silica particles, of a zirconium compound which is at least one selected from zirconium chloride and zirconyl chloride, and 30% by mass to 99.5% by mass of water. In accordance with the present invention, it is possible to provide an antifouling coating that can maintain the antifouling performance and hydrophilicity and prevent corrosion of fins even under an environment with a large amount of contaminating substances, such as metal particles, in the air.
