Note: Texte fondé sur des processus automatiques de reconnaissance optique de caractères. Seule la version PDF a une valeur juridique

CLAIMS
1. A method of preventing fouling of a marine struc ture characterised by securing to the underwater surface of the marine structure a coated flexible sheet material, the outermost surface of which is a layer of silicone rubber.
2. A method according to claim 1 characterised in that the silicone rubber is a cured room-temperature-vulcanisa silicone rubber.
3. A method according to claim 1 characterised in that the silicone rubber is a heat-cured silicone rubber.
4. A method according to any of claims 1 to 3 charac terised in that the silicone rubber is mixed with a silicone oil.
5. A method according to any of claims 1 to 3 charac terised in that the coated sheet material is a fabric which is coated with at least one inner layer of an elastomer

(other than silicone rubber) selected from natural rubber, neoprene rubber or chlorinated polyethylene rubber as well as an outermost layer of silicone rubber.
6. A method according to any of claims 1 to 3 charac terised in that the thickness of the silicone rubber layer is from a thickness equivalent to a coating weight of 10 grams per square metre up to a thickness of one millimetre.

7. An anti-fouling cladding for a marine structure composed of a coated flexible sheet material comprising a flexible substrate, optionally one or more inner coated layers of an elastomer and an outermost coated layer of a cured silicone rubber.
8. An anti-fouling cladding for a marine structure com prising a coated fabric, the outermost coated surface of which is a layer of a silicone rubber/silicone oil mixture produced by curing a room-temperature-vulcanisable silicone rubber having hydroxyl end groups in the presence of 1 to 50 per cent by weight of the silicone oil.
9. An anti-fouling cladding according to claim 8 char acterised in that the silicone oil is a methyl phenyl sili cone oil.

10. A marine structure having a reduced liability to fouling, characterised in that it has secured thereto at and/or below the waterline a coated flexible sheet material the outermost surface of which is a layer of silicone rubber.
