  • Fouling control composition comprising a polymer comprising silyl ester functional groups and quaternary ammonium/phosphonium groups
    Patent number: 10273323
    Abstract: The present invention relates to a polymer comprising (a1) silyl ester group(s) and (a2) quaternary ammonium group(s) and/or quaternary phosphonium group(s), said quaternary ammonium groups and/or quaternary phosphonium groups being neutralised by counter-ions, wherein the counter-ions consist of the conjugate base of an acid having an aliphatic, aromatic, or alkaryl hydrocarbyl group. The invention further relates to a fouling control coating composition comprising said polymer, 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.
    Type: Grant

  • Fouling Control Coating Composition Comprising a Polymer Containing Silyl Ester Groups, and a Polymer Comprising Quaternary Ammonium/Phosphonium Sulphonate Groups
    Publication number: 20170355861
    Abstract: 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.
