Abstract: A biocidal material includes a carrier, a plurality of copper-containing glass particles, and at least one co-biocide selected from isothiazolinones, bicyclic oxazolidines, and bromine nitrogen-based compounds. A minimum bactericidal concentration (MBC) of a combination of the at least one co-biocide and the plurality of copper-containing glass particles is less than an MBC of the at least one co-biocide in the absence of the plurality of copper-containing glass particles.

Abstract: A method for making an antimicrobial composite film can include forming a first coating layer by applying a first coating material on a substrate and forming a second coating layer by applying a second coating material on the first coating layer. The first coating material can comprise a first resin. The second coating material can comprise an antimicrobial material in a second resin or a dispersion. The first coating material can have a lower concentration of the antimicrobial material than the second coating material. The first and second coating layers can cooperatively define a composite film. The antimicrobial material can be asymmetrically dispersed in the composite film such that the antimicrobial material is concentrated closer to the outer surface of the composite film than to the inner surface of the composite film.

Abstract: A biocidal material and method of forming is provided. The biocidal material includes a carrier and a plurality of treated copper-containing particles including a particle surface pre-treatment. The surface pre-treatment includes a copper-chelating material.

Abstract: According to various examples of the present disclosure, a biocidal dispersion includes one or more inorganic glass comprising copper particles. The biocidal dispersion further includes a dispersant, a thickener, or a mixture thereof. The inorganic glass comprising copper is homogenously distributed about the biocidal dispersion and is in a range of from about 3 wt % to about 88 wt % of the biocidal dispersion.

Abstract: A composition for forming a biocidal coating is provided. The composition has a log reduction of at least 2 and a CIEL*a*b* delta E*value less than about 30.

Abstract: According to various examples of the present disclosure, an antimicrobial assembly includes a substrate comprising a matrix material having opposed first and second surfaces with a total thickness of the substrate defined therebetween. The assembly further includes an antimicrobial composition bound to the substrate and heterogeneously distributed about the antimicrobial assembly.
