Fluorine coating composition
Disclosed is a two-pack fluorine coating composition which comprises a combination of: a base component comprising a fluorinated copolymer having a hydroxyl group which can be dissolved in a low-polar weak solvent even at a low temperature and; a curing agent comprising a polyisocyanate compound. Specifically disclosed is a fluorine coating composition comprising: (A) a base component which comprises a fluorinated copolymer of a fluoroolefin and a monomer having a double bond copolymerizable with the fluoroolefin and which has a fluorine content of 10 mass % or more, wherein 5 to 30 mol % of the monomer has a hydroxyl group and 10 to 50 mol % of the monomer has a branched alkyl group having 3 or more carbon atoms; and (B) a curing agent comprising a polyisocyanate compound which is produced by the reaction between at least one diisocyanate selected from an aliphatic diisocyanate and a alicyclic diisocyanate and a monoalcohol having 1 to 20 carbon atoms and which has an [(allophanate group)/(isocyanurate group)] ratio of 90/10 to 81/19 by mole.
