Abstract

Methods of protecting a surface include applying an inner polymer layer onto a surface. The inner polymer layer is impregnated with a biologically active chemical substance that protects the surface from biofouling-induced chemical, biological, and bio-proliferative damage. The inner polymer layer is an epoxy polymer. An outer polymer layer is applied onto the inner polymer layer. The outer polymer layer is impregnated with a biologically active chemical substance that protects the inner polymer layer from biofouling-induced chemical, biological, and bio-proliferative damage. The outer polymer layer is selected from the group consisting of polyurethanes and fluorourethanes.
