The revised OPSITE◊ Post-Op dressings combine the features of the current OPSITE◊ Post-Op dressings with the high MVTR REACTIC◊ hydrophilic polyurethane film used to manufacture OPSITE◊ IV3000◊ Transparent Adhesive Film Dressings. The patented REACTIC◊ film is 3 to 8 times more permeable to water vapor than standard film dressings. It can "switch" in the presence of moisture allowing excess moisture to transpire off.
