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:&#x2014;{[CFR&#x2014;(CFR)&#x2014;(O)]&#x2014;[CFR&#x2014;O]}&#x2014;wherein n is 0 or 1, m is an integer from 0 to 4, R independently is H, F, Cl, Br, or CF, 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 &#x2014;[SiRR&#x2014;O]&#x2014;, wherein Rand Rare independently hydrogen, alkyl, aryl, aralkyl, or a vinyl group.
