  • Patent number: 7381860
    Abstract: A method for producing a wound dressing wherein a curable silicone mixture is extruded onto a generally planar molding surface. The silicone mixture defines a first surface adjacent the planar surface and a second surface opposite the first surface. The molding surface is heated at a curing temperature sufficient to cause the silicone mixture to cross-link. The silicone mixture is uniformly spread over the molding surface such that the silicone mixture has a generally uniform thickness and the second surface is substantially planar. The second surface of the silicone mixture is laminated to an absorbent material after the silicone mixture has started to cross-link and transform to a gel due to exposure to the heated molding surface.
