14 Claims

1. A fluorinated coating composition comprising

(A) one or more compounds selected from hydroxyl or hydrolyzable group-containing silanes and siloxanes which are modified with a fluorooxyalkylene-containing polymer, and partial (hydrolytic) condensates thereof, the fluorooxyalkylene-containing polymer residue in component (A) having a number average molecular weight of 1,500 to 10,000, and

(B) a fluorooxyalkylene-containing polymer-modified polysilazane composed of fluorooxyalkylene-containing polymer-modified silazane units, the fluorooxyalkylene-containing polymer residue in the fluorooxyalkylene-containing polymer-modified silazane units as component (B) having a number average molecular weight of 500 to 6,000, wherein

component (A) and component (B) are mixed in a weight ratio of from 10:90 to 90:10, provided that the total weight of components (A) and (B) is 100.
