Abstract: A silver-containing tissue dressing for providing antimicrobial properties to a wound site is disclosed. In some embodiments, the tissue dressing may include a wound contact layer having a substrate material coated with a tacky hydrophobic silicone material, and silver-containing particles dispersed in the silicone material. The different surfaces of the substrate material may be coated with the silicone material having various amounts of tackiness. The silver material may provide antimicrobial properties when the tissue dressing is placed in contact with the wound site.

Abstract: A wound dressing product that includes a substrate layer having an upper surface and a lower surface; a tacky silicone coating composition present on the upper surface and on the lower surface; and upper and lower release sheets covering the substrate and the tacky silicone coating composition on the upper and lower surfaces, respectively, and adhered to the surfaces by the tacky silicone coating composition, wherein the upper surface is less tacky than the lower surface whereby the upper release sheet can be removed from the upper surface more readily than the lower release sheet can be removed from the lower surface. Also provided are methods for making such dressings.
