Abstract
Coated substrates and methods may comprise a multi-unit carbodiimide. The multi-unit carbodiimide may also be combined with a siloxane. The multi-unit carbodiimide and/or the siloxane may be used in a surface coating applied to a substrate, and an overcoat may be applied to the surface coating. The surface coating may chemically interact with the overcoat and/or the substrate to improve corrosion resistance and other properties of the coated substrate.
