ABSTRACT:
A composite of a gel of swollen hydrocolloid dispersed in a pressure sensitive adhesive matrix is provided. The gel has a natural or synthetically derived hydrocolloid swollen with a non-volatile swelling agent, such that the gel may have a shear modulus of less than 6.2.times.10.sub.6 dynes/cm.sup.2 The gel-adhesive composite has continued skin adhesion whether applied to or existing in dry or moist skin conditions. The gel contributes a high moisture vapor transmission rate to attempt to maintain dry skin conditions while the adhesive maintains skin adhesion. The gel-adhesive composite may be used in a variety of tape, dressing, bandage, drape, or other skin contacting usage and may optionally include antimicrobial agents to treat the skin while adhesion continues.
