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 cmnull1 to the peak absorbance at 500 cm null1 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.

Abstract translation: 防水涂料具有四氟乙烯树脂粉末，硅树脂粘合剂和有机溶剂。 四氟乙烯树脂粉末在1,800cm -1处的峰值吸光度与500cm -1处的峰值吸光度的比值为0.0001〜0.05。 通过将这种涂层涂覆在基材上形成涂膜。 尽管没有大量的氟树脂粉末，该涂层具有高斥水性，优异的防冰涂层，优异的防雪涂层等性能。 另外，无论涂膜是否长时间浸入水中，膜的涂布保持防水性。
