ABSTRACT:
A method of protecting surfaces against deterioration by environmental factors is described. In a particular aspect of this invention a metal surface subject to electrochemical corrosion has applied to it a metal-plastic laminate comprising (a) a foil of corrosion-resistant metal, in particular lead; (b) a plastic film ranging up to about 20 mils in thickness, bonded to one surface of the metal foil, either by "extrusion coating" or by means of a suitable adhesive; and (c) a coating of pressure-sensitive adhesive on the opposite surface of the metal foil. (In some cases the outer plastic film can be omitted.) The laminate is bonded to the metal substrate by means of the pressure-sensitive adhesive. This method, when used in conjunction with a coating of anti-fouling paint, is effective for protecting the hull of a marine vessel both against corrosion and fouling by marine organisms such as barnacles; and the invention is also effective in protecting wooden vessels against marine borers. The method is relatively inexpensive and easy to carry out, and requires only a minimum of surface preparation of the substrate.
