摘要：
The present invention provides composition for treating a substrate comprising a homogeneous mixture of: (a) a fluorinated polyether silane of the formula: Rf1—[—Q—SiY3−xR1x]y (I) wherein Rf1 represents a monovalent or divalent polyfluoropolyether group, Q represents an organic divalent linking group, R1 represents a C1-C4 alkyl group, Y represents a hydrolysable group; x is 0 or 1 and y is 1 or 2; (b) an organic or an inorganic acid; (c) water; and (d) an organic solvent. The invention further provides a method of making such a composition and the use thereof to treat substrates to render them oil and water repellent.
