Aqueous antifouling agent for water system

Abstract

Abstract PURPOSE:To obtain the titled antifouling agent effective in suppressing the adhesion and proliferation of aquatic life in seawater and having high safety, by using a tetraalkyl ammonium chloride and a chlorophenol derivative as antifouling components and an aqueous resin emulsion as a binder. CONSTITUTION:The objective aqueous antifouling agent contains (A) an aqueous resin emulsion (especially preferably a resin selected from acrylic resin, urethane resin and vinyl acetate resin which forms a water-insoluble film by the evaporation of water) as a binder and (B) a tetraalkyl ammonium chloride and a chlorophenol derivative [especially preferably a compound selected from 2,4,4'- trichloro-2'-hydroxydiphenyl ether and bis(5-chloro-2-hydroxyphenyl)methane] as antifouling components. The weight ratio of the solid content of the emulsion to the solid content of the antifouling agent is preferably 10:(1-10).
