<p>A method for protecting surfaces of objects or constructions that are exposed to surface-water against growth of biological origin by applying an antifouling coating layer onto these surfaces, which coating layer is formed from a paint formulation composing (a) one or more water-insoluble polymeric binders, (b) one or more water-soluble polymeric binders, (c) one or more sparingly water-soluble toxicants, optionally completed with other conventional materials, whereby the proportion of the components (a), (b) and (c) is such that the resulting coating layer when exposed to the surface water, wears off at such a rate that just sufficient toxicant is liberated to prevent fouling of the protected subject.</p> |
