Novel organic fluorine compounds are of formula (1):n wherein R 1 and R 2 are monovalent hydrocarbon groups, Q 1 is a group of formula (2) or (3):n n wherein R 3 is a divalent hydrocarbon group which may have an intervening oxygen, nitrogen or silicon atom, R 4 and R 5 are divalent hydrocarbon groups, Rf 1 is a divalent perfluoroalkylene or perfluoropolyether group, and letter a is an integer of 0-10. A curable composition comprising (A) a fluorinated amide compound having at least two aliphatic unsaturated groups of formula (1), (B) a fluorinated organohydrogensiloxane containing at least one monovalent perfluoroalkyl ether or perfluoroalkyl group and at least two hydrosilyl groups, and (C) a platinum group compound cures into elastomers solvent and chemical resistance. |
