ABSTRACT:
A room temperature curable composition comprises a fluorine-containing organosilicon compound represented by the general formula: ##STR1## wherein a is an integer of at least 1, b is 2 or 3, each R.sup.1 is a monovalent unsubstituted or substituted hydrocarbon group, each R.sup.2 is a divalent hydrocarbon group, each R.sub.f is a divalent perfluoroalkylene group or a divalent perfluoroalkylether group, and Q is a divalent siloxane group (--Si--O--Si) having four pendant monovalent hydrocarbon groups bonded to silicon atoms. The composition can provide a cured product excellent in all of the solvent resistance, chemical resistance, heat resistance and cold resistance.
