Abstract
A water-repellent coating has tetrafluoroethylene resin powder, silicone resin binder, and organic solvent. The tetrafluoroethylene resin powder has a ratio of the peak absorbance at 1,800 cm to the peak absorbance at 500 cm of 0.0001 to 0.05 exclusive. A coating film is formed by applying such a coating on a substrate. The coating has the properties of high water repellency, excellent anti-ice-coating, excellent anti-snow-coating, and so on, in spite of not having a large amount of fluororesin powder. In addition, the coating of film keeps the water repellency regardless of whether the coating film is immersed into water for a long time.
