Abstract: An antifouling coating composition useful for coating fish netting, boat hulls, lumber, roof shingles and the like to prevent the growth of algae or fungi. The composition comprises a vinyl polymer or copolymer emulsion containing a dialkyldimethyl ammonium compound with or without an alkylbenzyldimethyl ammonium compound. The preparation of the composition must be done with care in order to prevent the added quaternary ammonium compound from destabilizing the emulsion polymer. The invention also relates to articles coated with the composition to prevent the formation of algae and fungi thereon.
