Mepilex Transfer Ag Antimicrobial Soft Silicone Exudate Transfer Dressing, Size 4 x 5. Mepilex Transfer Ag is a thin and conformable, antimicrobial wound contact layer. The Safetac technology layer ensures direct contact to the wound and the surrounding skin, including uneven surfaces. As the Safetac technology layer seals around the wound, the foam structure of Mepilex Transfer Ag allows exudate to move vertically into a secondary absorbent dressing. Mepilex Transfer Ag maintains a moist wound environment in combination with an appropriate secondary dressing.
