    • 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.degree. F. to about 200.degree. 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.degree. F. to about 200.degree. F. to further bind the composition to the 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.
    • 阳极氧化铝产品,以连续纤维网或片状形式,其被热密封并涂覆有抗微生物组合物。 抗微生物涂层可以结合到阳极层的表面,并且可以包含也共价结合到阳极层的表面的交联的有机硅烷分子的网络。 还提供了一种方法,包括:在铝基材的表面上形成阳极层; 热封阳极层; 将幅材或片材预热至约140度的范围。 F.到约200.degree。 F。; 以足以使组合物至少开始结合到阳极表面上并在阳极层上形成抗微生物涂层的施用速率施用抗微生物组合物; 并将涂覆的阳极氧化抗微生物纤维网或片材后加热至约140度的范围。 F.到约200.degree。 F.进一步结合组合物以固化抗微生物涂层。 任选地,可以蚀刻热密封阳极层以产生抗微生物组合物强力结合的粘合层。
