Abstract
A process to physically deter fouling from a substrate in an aquatic fouling environment, which process comprises forming on the substrate, before exposure to the said environment, a coating composition comprising (i) a curable polyorganosiloxane polyoxyalkylene block copolymer having at least two reactive groups X situated on the copolymer chain and (ii) an organosilicon crosslinking agent and/or a catalyst.

A process to physically deter fouling from a substrate in an aquatic fouling environment, which process comprises forming on the substrate, before exposure to the said environment, a coating composition comprising (i) a curable polyorganosiloxane polyoxyalkylene block copolymer having at least two reactive groups X situated on the copolymer chain and (ii) an organosilicon crosslinking agent and/or a catalyst.
A substrate coated with a coating obtainable by
- a) applying on the surface a coating composition comprising (i) a curable polyorganosiloxane polyoxyalkylene block copolymer having at least two reactive groups X situated on the copolymer and (ii) an organosilicon crosslinking agent and/or a catalyst and
- b) subsequently curing the coating composition.
