Abstract

Described is a metallized article, and a method for making the same, comprising a substrate having a polyurethane basecoat disposed thereon and with a layer of electrically discrete metallic islands of a corrosion prone metal disposed on the basecoat. A cross-linked polyurethane top coat, which is bound to an organosilane, preferably an epoxy silane, is disposed on and encapsulates the discrete metallic islands. The organsilane is also bound to the metallic islands.
