1. A dilutable, non-aqueous concentrate comprising a mixture of:
(a) at least one fluorinated oligomeric silane of the formula
A-MnfMmhMra-G
wherein:
A is hydrogen or a residue of an initiating species;
Mf represents units derived from one or more fluorinated monomers
Mh represents units derived from one or more non-fluorinated monomers;
Ma represents units derived from one or more non-fluorinated monomers having a silyl group, SiY3 where Y is a hydrolyzable silyl group; and
G is a residue of a chain transfer agent of the formula
—S-Q-Y3 in which Y is a hydrolysable group and Q is an organic divalent linking group;
n is an integer from 1 to 100;
m is an integer from 0 to 100; and
r is an integer from 0 to 100; and
(b) at least one surfactant selected from dicocomethylammonium chloride, alkylenediolpolyethylene glycols, alkylphenol-polyethylene
glycols, alkyleneoxy containing silicone oligomers and a mixture thereof.
