Abstract: An antimicrobial additive composition is provided which economically and efficiently imparts antimicrobial characteristics to acrylic polymers, and particularly thermoformable acrylic sheets made from such polymers. The antimicrobial composition comprises an alkyl dimethyl ammonium saccharinate, an oxathiazine, an azole, an isothiazoline, a chlorothalonil, and/or mixtures thereof, among others.
Abstract: An antimicrobial cementitious composition for imparting antimicrobial characteristics to cement comprises a cement-based compound and an imazalil agent; combinations of agents also may be employed.
Abstract: An antimicrobial ceramic glazing composition comprising zinc borate for imparting antimicrobial characteristics to numerous ceramic products. A method for producing the antimicrobial glazing composition and ceramic products incorporating the antimicrobial glazing composition.
Abstract: An antimicrobial cementitious composition for imparting antimicrobial characteristics to cement comprises cement and an antimicrobial agent selected from the group consisting of an ortho-phenyl phenol or salt thereof, a tolyl diiodomethyl sulfone, a zinc pyrithione, an oxathiazine, an azole, a chlorothalonil, and a triazine diamine; combinations of agents also may be employed.
Abstract: The invention is a radiation curable coating containing an antimicrobial agent, where upon irradiation with UV light, the radiation curable coating rapidly cures to a polymeric coating. The polymeric coating has durable antimicrobial properties, being especially effective at preventing the growth of Staphylococcus aureaus and Kleibsella pneumoniae on wood flooring and furniture. The major components in the radiation curable coating are a urethane acrylic oligomer, a radiation cure package, an antimicrobial agent, a cross-linking agent, and optionally, an additive package. The radiation curable urethane oligomer is a relatively short chain backbone urethane polymer that is end capped with a radiation curable moiety, where the moiety is an acrylic. The cross-linking agent is one or more monomers used to lower the viscosity and promote cross-linking, and include acrylate esters of mono-, di-, tri-, or tetrafunctional alcohols. The radiation cure package contains at least one photoinitiator.
