Abstract

A room temperature curable composition comprising: PA1 (A) a fluorine-containing organosilicon compound having the formula (1): EQU R.sup.2 --NHCO--[Rf.sup.1 --CONH--R.sup.1 --Q--R.sup.1 --NHCO].sub.a --Rf.sup.1 --CONH--R.sup.2 (1) PA1 wherein a is an integer of 0 or more, Rf.sup.1 is a perfluoroalkylene group or perfluoropolyether group, R.sup.1 is a divalent hydrocarbon group, R.sup.2 is a monovalent aliphatic unsaturated hydrocarbon group, and Q is a particular organosilicon group, PA1 (B) an organohydrogenpolysiloxane containing at least two Si--H groups in its molecule, and PA1 (C) a platinum family metal compound, the component (B) being contained such that the Si--H groups are contained in an amount of 0.5 to 5.0 moles per mole of the aliphatic unsaturated hydrocarbon group contained in the composition. The composition produces a cured product having good solvent resistance, chemical resistance, heat resistance and cold resistance.
