Building material coating

摘要

A corrosion-resistant colored architectural material which is essentially lead free and is not highly reflective. The coating on the material is a two-phase metallic coating comprised of a large weight percentage of zinc and a relatively large weight percentage of tin. The tin-zinc coating may also include nickel and copper. The tin-zinc composition provides for both a highly corrosive-resistant coating which protects the surface of the architectural material from oxidation and also produces a gray, earth tone colored which is not highly reflective.
