摘要：
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.
