Beschreibung
Zusammenfassung:The present invention relates to a fouling control coating composition comprising an ingredient having biocidal properties for aquatic organisms and (a1) a polymer comprising quaternary ammonium groups and/or quaternary phosphonium groups bound to the backbone of the polymer, said quaternary ammonium groups and/or quaternary phosphonium groups being neutralised by a conjugate base of a sulphonic acid having an aliphatic, aromatic, or alkaryl hydrocarbyl group, and (a2) a polymer comprising silyl ester groups. The invention further relates to a method of protecting a man-made structure immersed in water from fouling, and a substrate or structure coated with the fouling control coating composition.
