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.

A wound dressing product, comprising:
- a substrate layer having an upper surface and a lower surface;
- and
- a tacky silicone coating composition present on said upper surface and on said lower surface;
- wherein
- said tacky silicone coating composition is present in a greater weight on said upper surface than on said lower surface of said substrate layer;
- said upper surface is more tacky than said lower surface;
- and
- a tackiness of said upper surface as measured by a loop tack test is at from 20% to 100% greater than a tackiness of said lower surface.
A wound dressing product comprising:
- a substrate layer having an upper surface and a lower surface;
- a tacky silicone coating composition present on said upper surface and on said lower surface;
- and
- upper and lower release sheets covering said substrate layer and said tacky silicone coating composition on said upper surface and said lower surface, respectively, and adhered to said surfaces by said tacky silicone coating composition,
- wherein the silicone coating composition on said upper surface is less tacky than the silicone coating composition on said lower surface whereby said upper release sheet can be removed from said upper surface more readily than said lower release sheet can be removed from said lower surface,
- wherein a tackiness of the lower surface as measured by a loop tack test is at from 20% to 100% greater than a tackiness of the upper surface.
