- 9. The curable composition according to claim 1, wherein the curing agent is a polyol-modified polyisocyanate.
- 10. The curable composition according to claim 1, which further contains a filler.
- 11. The curable composition according to claim 10, wherein the filler is contained in an amount of from 1 to 500 parts by weight per 100 parts by weight of the fluorine-containing copolymer.
- 12. The curable composition according to claim 10, wherein the filler is selected from the group consisting of fumed silica, precipitated silica, silicic anhydride, hydrous silicic acid, carbon black, surface-treated fine calcium carbonate, surface-treated aluminum hydroxide, calcined clay, clay, titanium oxide, calcium carbonate, magnesium carbonate, talc, ferric oxide, zinc oxide and silica balloons.
- 13. A curable composition containing a fluorine-containing copolymer having fluidity at room temperature and comprising, based on entire polymer units, from 20 to 70 mol % of polymer units (1) derived from a fluoroolefin and from 1 to 80 mol % of polymer units (2") having a polyoxyalkylene chain having, at its terminal, a functional group cross-linkable by the action of moisture, the total of the polymer units (1) and the polymer units (2") being from 30 to 100 mol %.
- 14. The curable composition according to claim 13, wherein the functional group cross-linkable by the action of moisture is a group selected from the group consisting of an isocyanate group, a hydrolyzable silyl group and a thiol group.
- 15. The curable composition according to claim 13, wherein the polyoxyalkylene chain is a polyoxyalkylene chain having from 5 to 50 oxyalkylene units.
- 16. The curable composition according to claim 13, wherein the polyoxyalkylene chain is composed of oxyalkylene units having from 2 to 8 carbon atoms.
- 17. The curable composition according to claim 13, wherein the fluorine-containing copolymer has a viscosity of from 300 to 100,000 centipoise at 25.degree. C.
- 18. The curable composition according to claim 13, which further contains a filler.
- 19. The curable composition according to claim 18, wherein the filler is contained in an amount of from 1 to 500 parts by weight per 100 parts by weight of the fluorine-containing copolymer.
- 20. The curable composition according to claim 18, wherein the filler is selected from the group consisting of fumed silica, precipitated silica, silicic anhydride, hydrous silicic acid, carbon black, surface-treated fine calcium carbonate, calcined clay, clay, titanium oxide, magnesium carbonate, talc, ferric oxide, zinc oxide and silica balloons.
