  • Patent number: 5331074
    Abstract: Silicone rubber coatings resistant to fouling by aquatic organisms are based on a hydroxy-functional polydiorganosiloxane and a crosslinking agent therefor. The hydroxy-functional polydiorganosiloxane may be packaged separately from the crosslinking agent, or a stable package comprising a hydroxy-functional polydiorganosiloxane terminated by excess crosslinking agent may be packaged separately from further hydroxy-functional polydiorganosiloxane. In either case the two packages can be combined to give the optimum ratio of crosslinking agent to silicon-bonded hydroxyl groups to ensure cure and give optimum resistance to fouling, whilst overcoming the problem of premature gelation during storage.

  • Patent number: 5290601
    Abstract: A primer composition for application to a substrate to promote adhesion of a room-temperature-vulcanizable silicone rubber coating, comprises (A) an aminosilane material, (B) a chlorinated polyolefin and (C) a room-temperature-curable polydiorganosiloxane. The aminosilane material (A) is a primary amine-functional silane or the reaction product of a primary amine-functional silane with an epoxy-functional silane or an alpha, omega-dihydroxypolydimethylsiloxane oil.

  • Patent number: 5192603
    Abstract: A process for protecting a rigid substrate against aquatic fouling comprises coating the substrate with an elastomeric undercoat as a 200 to 1500 micron thick layer and with a top coat of a room temperature vulcanisable silicone rubber. The elastomeric undercoat is generally harder than the room temperature vulcanisable silicone rubber foul resistant top coat and preferably has a Shore A hardness of 60 to 90 and an extensibility of 200 to 800%. The abrasion and tear resistance of the silicone rubber foul resistant layer is markedly increased by the use of the elastomeric undercoat.
