ABSTRACT:
A curable silicone composition, comprising (A) a fluorosilicone represented by the following general formula (1): ##STR1## wherein Rf represents a perfluoroalkylene group or perfluoropolyether group having 11 to 30 carbon atoms, R.sup.1, R.sup.2, and R.sup.3 each represent a monovalent hydrocarbon group, a and p are each an integer of 2 or over, b and c are each an integer of 0 or over, and X is a triorganosilyl group, (B) an organohydrogensiloxane containing two or more Si--H groups in the molecule, and (C) a platinum family metal catalyst. This composition upon curing gives a rubberlike elastic product excellent in solvent resistance, chemical resistance, water repellency, and oil repellency and low in moisture permeability.
