Abstract

The present invention relates to a non-aqueous liquid foul release coating composition for controlling aqueous biofouling on man-made objects, comprising a curable resin system (A) comprising i) a curable polymer free of fluorine atoms and having a backbone selected from a polyurethane, a polyether, a polyester, a polycarbonate or a hybrid of two or more thereof, and having at least one terminal or pendant alkoxysilyl group and ii) optionally a curing agent and/or a catalyst; and (B) a marine biocide and/or a non-curable, non-volatile compound is selected from the group consisting of fluorinated polymers, sterols and sterol derivatives, and hydrophilic-modified polysiloxane oils, wherein the coating composition is essentially free of a curable polysiloxane, and wherein the coating composition is essentially free of non- curable polysiloxanes other than non-curable hydrophilic-modified polysiloxane oils. The invention further relates to a substrate coated with such foul release coating composition, to a process for controlling aquatic biofouling on a surface of a man-made object using such coating composition and to the use of such coating composition for controlling aquatic biofouling on a surface of a man- made object
