Abstract: A method of making a wound dressing comprising the steps of: providing an apertured substrate layer; coating the substrate layer with a fluid silicone prepolymer composition; thermally partially curing said silicone prepolymer composition to form a partially cured silicone coating on the substrate; laminating the coated substrate layer to a base layer to form a laminate having said partially cured silicone coating in contact with a surface of the base layer; followed by exposing the laminate to ionizing radiation, to further cure the partially cured silicone coating and to bond the silicone coating to said surface of the base layer. The radiation cure results in strong bonding between the siliconized substrate and incompatible base layers such as polyurethane foams. Also provided are wound dressings obtainable by the process of the invention.

Abstract: 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 and said tacky silicone coating composition on said upper and lower surfaces, respectively, and adhered to said surfaces by said tacky silicone coating composition, wherein said upper surface is less tacky than 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. The same silicone composition is used to form both the upper and the lower surface. Also provided are methods for making such dressings.

Abstract: A method of applying a patterned coating of a silicone adhesive to a substrate sheet, comprising the steps of pattern coating a silicone precursor composition onto the substrate, followed by thermally curing the precursor composition coated on the substrate. The precursor composition is a viscous fluid, and the pattern coating is performed by suitably modified block printing, intaglio printing or screen printing methods. Also provided are coated substrates obtainable by the methods of the invention, and wound dressings comprising such coated substrates.
