Abstract: The invention is directed to curable polyurethane coating compositions which may be used to form fouling release coatings, e.g., for use in protecting boat hulls. A curable coating composition of the invention comprises a) at least one amphiphilic additive; b) at least one polyisocyanate; c) at least one polyol; and d) optionally, at least one amphiphilic PEG-PDMS isocyanate prepolymer. Another curable coating composition of the invention comprises the at least one polyisocyanate, b), the at least one polyol, c), and the at least one amphiphilic PEG-PDMS isocyanate prepolymer, d). The invention further relates to methods for reducing or preventing biofouling of a surface exposed to an aqueous environment comprising the steps of coating the surface with the curable coating compositions of the invention to form a coated surface, and curing the coating composition on the coated surface.
