<p>A water repellent coating composition comprises a fluororesin powder having a specific surface area ranging from 27 to 48 m2/g and a molecular weight ranging from 10,000 to 100,000; an acrylic-silicone binder resin; and a solvent. The fluororesin may be preferably at least one resin selected from polytetrafluoroethylene resins, tetrafluoroethylene/perfluoro(alkyl vinyl ether) copolymer resins, and tetrafluoroethylene/hexafluoropropylene copolymer resins. The coating composition can be used in various fields including constructions, civil engineering, transportation, communication. The coating films and coated articles produced with the water repellent coating composition exhibit excellent water repellency, antisnow- or antiice-sticking properties, and weatherability.</p> |
