Foul preventing coating composition

The invention relates to a coating composition for use as a coating to prevent fouling in a marine environment, comprising: a) a curable polysiloxane polyoxyalkylene block copolymer; b) a catalyst of general formula (i) wherein each Ris independently a monovalent hydrocarbon group, each Ris independently selected from a hydrogen atom, a monovalent organic group, a siloxane group, or a silyl group of formula &#x2014;SiR, wherein each Ris independently a monovalent hydrocarbon group, and n is an integer having a value of 0 or greater, and optionally: c) a filler and/or pigment. 

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.
