ABSTRACT:
Curable or vulcanizable fluorinated silicone compositions which comprise a uniform mixture of predetermined amounts of an organopolysiloxane of the following average unit formula ##STR1## in which R.sup.1 represents a monovalent hydrocarbon group having from 1 to 8 carbon atoms, and a and b are, respectively, a defined value; an organohydrogenpolysiloxane having at least three SiH groups in one molecule and consisting of the several siloxane units; and a catalytic amount of a platinum compound. If necessary, another type of polysiloxane may be added to the above composition in order to further improve physical properties. The composition is rapidly vulcanized to give a cured product having stable physical properties within a short time.
