ABSTRACT:
An article having a sealed layered edge, e.g. an automotive laminate and a multiple glazed unit includes a pair of glass sheet in a fixed relationship with one another. A sputtered coating is deposited on a major surface of one of the sheets and includes at least one combination of a metal film, e.g. a silver film and a dielectric film. Discontinuities in the metal film at the marginal edges of the coated sheet provide voids in the metal film to impede or stop corrosion of the metal film. The discontinuities include (1) break lines or segments in the coating, (2) coating thickness variations provided by abrading the coating and (3) spaced discrete coating areas on the marginal edges of the coated sheet. The discontinuities may be made in the metal film using a laser, an abrasive surface, a coating mask and/or coating deletion techniques.
