Viscosity of contact layer: Protect nerve endings of the wound and reduce friction.

The water-absorbing particles dispersed in the contact layer will form a gel layer to lock water after the contact with wound exudate, which will create an ideal moist space conducive to wound healing.

After the dressing absorbs moisture, the binding force with the wound surface will be reduced, and the secondary harm to the wound surface will not be caused during the dressing change.
