Abstract
An anti-fouling composition which comprises a cured or cross-linked polymer free of perfluoropolyether moieties and a fluid fluorinated alkyl- or alkoxy-containing polymer or oligomer. Preferably, the fluorinated alkyl- or alkoxy-containing polymer or oligomer comprises a repeating unit of the general formula:—{[CFR—(CFR)m—(O)n]p—[CFR—O]q}—wherein n is 0 or 1, m is an integer from 0 to 4, R independently is H, F, Cl, Br, or CF3, and the ratio q/p is 0-10, and the fluorine-free polymer is an organosiloxane-containing polymer comprising a repeating unit of the general structure —[SiR1R2—O]—, wherein R1 and R2 are independently hydrogen, alkyl, aryl, aralkyl, or a vinyl group.
