4 / FOULING CONTROL COATING COMPOSTION COMPRISING A POLYMER CONTAINING SILYL ESTER GROUPS AND A POLYMER COMPRISING QUATERNARY AMMONIUM/PHOSPHONIUM SULPHONATE GROUPS

摘要

The present invention relates to a fouling control coating composition comprising a component having a biocidal property with respect to an organism in water and (a1) a quaternary ammonium group bonded to the polymer backbone and / or A polymer comprising a quaternary phosphonium group, wherein the quaternary ammonium group and / or the quaternary phosphonium group is a polymer neutralized by a conjugate base of a sulfonic acid having an aliphatic, aromatic or alkaryl hydrocarbyl group, and (a2) a silyl ester group. Furthermore, the present invention relates to a method of protecting artificial structures that are submerged in water from fouling, and to substrates or structures coated with such a fouling control coating composition.
