Abstract
The invention herein relates to the method and use in an antifouling paint that specifically and efficiently impede settlement of for example barnacles on aquatic structures, using imidazole containing compound, such as Medetomidine, bound to a sulfonated, acid sulphate ester, phosphonic acid, carboxylic acid or acid phosphate ester modified polymer backbone such as polystyrene or acrylate polymers. The aim is to employ the biocide-polymer complexes as additives in a self-polishing paint for controlled release purposes.
Claims14
A method of preventing marine biofouling of a substrate by a marine biofouling organism, comprising applying a protective coating to the substrate, said coating containing an imidazole-containing compound bound to a polymer backbone selected from the group consisting of polystyrene and acrylate polymers, said polymer backbone modified by being bound to a sulfonated substance.
