Patent ID: 8344071

Claim:
A fluorine coating composition comprising: (A) a base component comprising a copolymer of a fluoroolefin and at least two double bond-containing monomers copolymerizable with the fluoroolefin, wherein the copolymer has a fluorine content of 10% by mass or more based on the fluoroolefin, and the at least two double bond-containing monomers comprise 5 to 30% by mol of a monomer containing a hydroxyl group and 10 to 50% by mol of a monomer containing a branched alkyl group having 3 or more carbon atoms; and (B) a curing agent comprising a polyisocyanate compound having a number average functional group number of from 2.10 to 2.50, produced by the reaction of a non-cyclic aliphatic diisocyanate with a monoalcohol having 1 to 20 carbon atoms and has a molar ratio of an allophanate group to an isocyanurate group in the range from 90:10 to 81:19.
