摘要： The invention relates to a coating composition comprising a) seawater-hydrolyzable groups covalently linked to a polymer backbone, which seawater-hydrolyzable groups are capable of undergoing hydrolysis or ion-exchange when exposed to sea-water, rendering the polymer partially soluble or dispersible in seawater, and b) zwitterionic groups covalently linked to a polymer backbone wherein the polymer backbones to which the sea-water-hydrolyzable groups and the zwitterionic groups are attached serve as a film-forming binder in the coating composition, and wherein the molar ratio of the seawater-hydrolyzable groups a) to the zwitterionic groups b) is 0.1 or higher. The invention also relates to a method of providing a substrate with anti-fouling performance and to a coated substrate.

摘要： The present invention relates to an antifouling coating composition comprising an ingredient having marine biocidal properties, and at least two different copolymers comprising salt groups. The antifouling coating composition has excellent antifouling properties. The present invention also relates to a method of providing a substrate with antifouling performance in an aqueous environment, and the use of the antifouling coating composition for protection of man-made structures immersed in water.
