Abstract
Abstract A wound dressing comprises, in one embodiment, a layer of apertured material, such as a cotton gauze, coated with a tacky silicone gel or a non-tacky silicone elastomer. In an alternative embodiment, the dressing has a tacky silicone gel on one surface and a non-tacky silicone elastomer on the other surface. The gel and elastomer may be formed by crosslinking a mixture of a vinyl-substituted poly(dimethylsiloxane) and a hydride-containing poly(dimethylsiloxane).
