The invention relates to a method of imparting anti-pathogenic properties to a substrate material comprising: (a) preparing a coating composition containing an anti-pathogenic agent consisting essentially of PVP-I and N-9 in a ratio of from about 100:0 to about 0:100 of PVP-I to N-9, the coating composition further containing a pre-mix solution with which the anti-pathogenic agent is intimately mixed in a ratio of from about 6:4 to about 8:2 of agent to pre-mix on a dry basis, and having a percent solids content of from about 5% to about 35% solids; (b) feeding the anti-pathogenic coating composition into a coating machine; (c) loading substrate onto the coating machine; (d) operating the coating machine such that the coating composition comes into intimate contact with at least one surface of the substrate; and (e) drying the coated substrate material. The invention further relates to the preparation of coating composition and to the composition itself.
A method of imparting anti-pathogenic properties to a substrate material wherein said method includes preparation of an anti-pathogenic coating solution and subsequently using said coating solution to coat said substrate, said method comprising:
A process for producing a substrate coated with a formulation containing an anti-pathogenic component comprising:
A coated substrate comprising a substrate material in intimate contact with an anti-pathogenic agent-containing solution characterized by the ability to release an anti-pathogenic agent immediately upon contact with a solution-borne pathogen to eliminate substantially immediately the pathogenic activity of the pathogen, wherein the anti-pathogenic agent-containing solution comprises (a) from about 30% by weight to about 80% by weight of an anti-pathogenic agent comprising a solution containing PVP-I and N-9;
An anti-pathogenic solution comprising a solution characterized by a % solids of 31.4% and the inclusion of a solution of PVP-I and N-9 as the active anti-pathogenic agent, the components of the solution being present in a ratio of from about 100:0 to about 0:100 PVP-I:N-9 and further including premix solution, wherein on a wet weight basis the anti-pathogenic agent solution comprises 71.5% by weight active anti-pathogenic agent and 28.5% by weight premix solution, and further wherein the active anti-pathogenic agent comprises 93.3% by weight PVP-I and 6.7% by weight N-9 and the premix solution comprises 54.6% by weight polyethylene glycol solution in distilled water and ethanol, 5.4% by weight polyoxyethylene sorbitan monoolete, 11.5% by weight talc, and 21.3% by weight ethanol solvent or the equivalent dry weight for each component consistent with the recited % solids, the anti-pathogenic solution exhibiting a viscosity between about 90 cps and about 130 cps, the solution substantially completely eliminating pathogens from a surface upon contact.
A process for preparing an anti-pathogenic coating composition for coating paper, plastic, woven and non-woven substrates and combinations thereof, comprising:
