Abstract
Biocidal metallic compositions and films, and methods for making and adhering biocidal compositions and films to surfaces requiring continued protection without requiring frequent cleaning are disclosed. The biocidal compositions may include metals, such as copper or silver powder, which are applied to the exposed surface of a variety of different resins, glues, epoxies, solvents or other surface treatments to create a biocidal film over the surface of product substrates including metals, leathers, papers, plastics, cardstocks, and glass surfaces.
