ABSTRACT:
A silicone composition having utility as an oil and water repellent coating for substrates when cured thereon is disclosed, said composition comprising:
(A) 100 parts by weight of an organopolysiloxane that has a viscosity at 25.degree. C. of at least 40 centipoise and that contains at least 2 alkenyl groups in each molecule;
(B) from 0.1 to 40 parts by weight of an organohydrogenpolysiloxane that contains at least 2 silicon-bonded hydrogen atoms in each molecule;
(C) from 0.01 to 10 parts by weight of a perfluoroalkyl-containing organosilane having the general formula ##STR1## wherein R.sup.1 represents a monovalent hydrocarbon group, R.sup.2 represents a divalent hydrocarbon group, a is 2 or 3, and n is a number having a value of 4 to 12, with the proviso that R.sup.1 is not an alkenyl group; and
(D) a catalytic quantity of a hydrosilylation-reaction catalyst.
