ABSTRACT:
The organopolysiloxane composition proposed is a blend of a conventional diorganopolysiloxane or a dimethylpolysiloxane oil and a limited amount of an (etherified) perfluoroalkyl group-containing organopolysiloxane such as those represented by the general formula ##STR1## in which Rf is a perfluoroalkyl group of 1 to 14 carbon atoms or an etherified perfluoroalkyl group of 2 to 14 carbon atoms having at least one oxygen atom between two carbon atoms forming an ether linkage, R is a hydrogen atom or a monovalent hydrocarbon group having 1 to 10 carbon atoms, Y is a divalent organic group having 2 to 5 carbon atoms, the subscripts a and b are, each independently from the other, zero or a positive integer and the subscripts c and d are, each independently from the other, zero, 1, 2 or 3 with the proviso that at least one of the subscripts a, c and d is not zero. By virtue of the admixture of this unique adjuvant, the silicone oil composition can be imparted with greatly increased spreadability even on the surface of a fluorocarbon resin film although the surface tension of the oil is not remarkably decreased thereby.
