Abstract

A coated substrate includes: a substrate; an electrically conductive multilayer stack on the substrate; and a coating on the electrically conductive multilayer stack. A thickness of the coating is 5 to 10 mils and the coating includes a conductive, anti-static tiecoat on the electrically conductive multilayer stack; and a conductive, anti-static topcoat on the conductive, anti-static tiecoat. The conductive, anti-static tiecoat and the conductive, anti-static topcoat are formed from a coating composition including a hydrophobic first aliphatic polyisocyanate, a second aliphatic polyisocyanate including a hydrophilic portion, a polyester polyol, a hydrophilic polyol, and a fluorinated polyol compound is disclosed.
