Patent

CA 2362569

Disclosed are marine antifouling compositions and/or paints containing hydrolytic enzyme(s), microorganism(s), or mixtures of the hydrolytic enzyme(s) and microorganism(s), wherein the microorganism or hydrolytic enzyme reduce fouling of a surface coated by the marine antifouling composition and/or paint. Such compositions and/or paints may contain a catalytically effective amount of an inorganic salt. Also disclosed are articles coated with the composition and/or paint. Finally, methods are disclosed for reducing fouling of a marine surface, for reducing marine corrosion, for limiting absorption of water by a marine surface, for reducing the coefficient of drag of a marine surface, removing marine growth from a marine surface, and for reducing mildew fungus on a marine surface.

Compositions et/ou peintures marines contenant une ou plusieurs enzymes hydrolytiques, un ou plusieurs micro-organismes, ou des mélanges desdites enzymes et desdits micro-organismes, le micro-organisme ou l'enzyme hydrolytique réduisant la salissure d'une surface couverte par ladite composition et/ou peinture marine. Lesdites compositions et/ou peintures peuvent contenir une quantité catalytiquement efficace d'un sel inorganique. La présente invention concerne également des articles couverts à l'aide de ladite composition et/ou peinture. Elle concerne enfin des procédés permettant de réduire la salissure d'une surface marine, de réduire la corrosion marine, de limiter l'absorption d'eau par une surface marine, de réduire le coefficient de traînée d'une surface marine, d'enlever la croissance végétale marine d'une surface marine, et de réduire la moisissure sur une surface marine.
