The active surface of the dressing is coated with a cross-linked adhesive mass containing a dispersion of gelatin, pectin and carboxy-methylcellulose together with other polymers and adhesives forming a flexible wafer. In contact with wound exudate, the polysaccharides and other polymers absorb water and swell, forming a gel. The gel may be designed to drain, or to remain within the structure of the adhesive matrix.
The moist conditions produced under the dressing are intended to promote fibrinolysis, angiogenesis and wound healing, without causing softening and breaking down of tissue. The gel which is formed as a result of the absorption of wound exudate is held in place within the structure of the adhesive matrix. Most hydrocolloid dressings are waterproof, allowing normal washing and bathing.
