Patent attributes
A mixed coating material includes: a cold curing resin that undergoes reaction curing at normal room temperature; and a particulate fluororesin. The constituent ratio of the particulate fluororesin in a coating film that is a cured state of the mixed coating material is 43 wt % or more and 82 wt % or less. A wing includes a non-water-repellent coating film that forms an outermost layer in a water droplet impact region in a leading edge portion of the wing; and a water-repellent coating film that is formed of the mixed coating material and that forms an outermost layer in a water-repellent region adjacent to the water droplet impact region P. An anti-icing system includes the wing and a heating unit that heats the water droplet impact region.
