Zusammenfassung: | An antifouling coating composition comprising: (i) a polymeric binder component comprising a plurality of ester functional groups; (ϋ) a plurality of core-shell polymer particles wherein the core comprises an organic biocide and a polymer of one or more ethylenically unsaturated monomers wherein at least one of said ethylenically unsaturated monomers comprises a polar group selected from hydroxyl, carboxylic acid, ether, sulfonic acid, amino or amido and wherein said polymer comprises more than 30 % by weight of monomer residues comprising polar groups; and a shell polymeric dispersant comprising a polymer of one or more ethylenically unsaturated monomers wherein said polymeric dispersant comprises less than 20 % by weight of ethylenically unsaturated monomer residues comprising polar groups selected from hydroxyl, carboxylic acid, ether, sulfonic acid, amino or amido; and (iii) optionally, an additional biocide. |
