ABSTRACT:
The invention provides a novel coating composition comprising a first component (i.e. 100 parts by weight of a fluorine-containing copolymer), a second component (i.e. 0.1-20 parts by weight of an alkyl silicate), and a third component (i.e. 0.05-3 parts by weight of a water-soluble polyether-modified silicone oil and/or 1-25 parts by weight of a polyoxytetramethylene glycol). The fluorine-containing copolymer has a hydroxyl value of 80-200 mg KOH per 1g thereof and is prepared by copolymerizing 40-65 mol % of a fluoroolefin, 14-50 mo1% of a copolymerizable vinyl-containing compound, 12-25 mol % of a polymerizable hydroxyl-containing compound, and 0.1-12 mol % of at least one other copolymerizable compound. A cured coated film prepared from the coating composition is superior in elasticity and weathering and stain resistances.
