  • Patent number: 6929705
    Abstract: The present invention relates to metallic sheets having an improved antimicrobial property and also related to a method of manufacturing such sheets. More particularly, it relates to the continuous coating on metallic sheets with a resin composition containing antimicrobial additives. The surface of the metallic article is afforded antimicrobial properties by coating a liquid dispersion or solution of fine particles made of an antimicrobial ingredient on the surface of the metallic sheet dispersed in a uniform layer and cured or dried to affix to the metallic surface. The inorganic antibacterial particles are metal component-supporting oxides and zeolite powders. The inorganic antibacterial core particles have at least a primary surface coating of at least one metal or metal compound having antimicrobial properties. Roll coaters apply the coating.
