Abstract
An anodized aluminum sheet, which is heat sealed and coated with an antimicrobial composition. The antimicrobial coating may be bound to the surface of the anodic layer and can comprise a network of cross-linked organo-silane molecules that are also covalently bound to the surface of the anodic layer. A process also is provided including: forming an anodic layer on the surface of an aluminum substrate; heat sealing the anodic layer; preheating the sheet; applying an antimicrobial composition at an application rate sufficient for the composition to at least begin binding to the surface of and form an antimicrobial coating over the anodic layer; and post heating the coated anodized antimicrobial sheet to further bind the composition to cure the antimicrobial coating. Optionally, the heat sealed anodic layer can be etched to create a bonding layer to which the antimicrobial composition strongly bonds.
