Abstract:
The present application discloses a fouling control coating composition comprising a polysiloxane-based binder system, 0.01-20% by dry weight of one or more hydrophilic-modified polysiloxanes, and one or more biocides. The hydrophilic-modified polysiloxane may be a poly(oxyalkylene)-modified polysiloxane, e.g. a polysiloxane having grafted thereto poly(oxyalkylene) chains and/or having incorporated in the backbone thereof poly(oxyalkylene) chains. The poly(oxyalkylene) may e.g. be selected from polyoxyethylene, polyoxypropylene and poly(oxyethylene-co-oxypropylene) (polyethylene glycols/polypropylene glycols). The application further discloses a marine structure comprising on at least a part of the outer surface thereof an outermost coating prepared from the coating composition. Moreover, the application discloses the use of the combination of non-reactive hydrophilic-modified polysiloxanes and biocides, wherein the weight ratio between the hydrophilic-modified polysiloxanes and the biocides is in the range 1:0.2 to 1:6, for improving the antifouling properties of a polysiloxane based coating composition.
