Abstract
An anodized aluminum product in continuous web or sheet form, which is heat sealed and coated with an antimicrobial composition. The antimicrobial coating can be bound to 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 web or sheet to a range from about 140° F. to about 200° F.; 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 web or sheet to a range from about 140° F. to about 200° F. to further bind the composition to the cure the antimicrobial coating.
