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. The metallic article generally includes sheet articles made of metals, for example, metallic sheets made of stainless steel, conventional steel sheets and aluminum sheets or plate.

A method of colorizing stainless steel strip involves the continuous surface treatment of stainless steel strip with aqueous suspensions of rare earth oxide nano or micro particles or aqueous rare earth nitrate solutions of nano or micro particles. The surface treatment can be applied by roll coating, spraying or other conventional application techniques. The coated strip is then continuously annealed. The surface treatment can provide a variety of colors. It also improves corrosion resistance of the processed stainless steel strip. Steel strip treated in this manner is suitable for a variety of applications in the building systems, automotive and appliance markets.

A process involves the continuous surface treatment of stainless steel coils with aqueous suspensions of rare earth oxide nano or micro particles or aqueous rare earth nitrate solutions of nano or micro particles. The surface treatment can be applied by roll coating, spraying or other conventional application techniques. The treated material in coil form is then heated in an annealing box using an open coil process whereby a wire is placed between coil laps to promote uniform atmosphere exposure. The atmosphere can be reducing or oxidizing and the times can vary from 1 hr to 100 hr. The atmosphere can also be wet (high dew point) or dry (low dew point). The surface treatment promotes a more uniform color to the subsequently developed oxide formed during anneal-type heat treatment. It also improves corrosion resistance of the processed stainless steel material. Materials treated in this manner are suitable for a variety of applications in the building systems, automotive and appliance markets.
