Abstract: The present embodiments relate to an antifouling article comprising polyurethane and medetomidine, or an enantiomer or salt thereof, from 0.1% by weight of the antifouling article and present in a polymer matrix of the polyurethane.
Abstract: This invention relates to the use of a combination of selected substances in paint to prevent the settlement and growth of different biofouling organisms with a reduced negative effect on the ecosystems compared to present methods.
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.

Abstract: This invention relates to the use of a combination of selected substances in paint to prevent the settlement and growth of different biofouling organisms with a reduced negative effect on the ecosystems compared to present methods.
Abstract: The use of an aromatic compound substituted with at least one heterocyclic amine and possibly additional substituents, such as medetomidine and clonidine, or a functionally analogous derivative thereof, as an agent for the inhibition of marine biofouling on a surface, by application thereon of said compound, is disclosed. Also a method for inhibition of marine biofouling on a surface by application of said compound is disclosed.
