The active surface of the dressing is coated with a cross-linked adhesive mass containing a dispersion of gelatin, pectin and carboxymethyl cellulose together with other polymers and adhesives forming a flexible wafer.

It has high water content, thus provides moisture and cooling effect for the wound. The dressing is easy to remove from the wound without causing any damage.
Hydrogel dressings can adhere directly to the wound bed under normal physiological conditions via oxidation-reduction reactions of quinones. [ 2 ] [ 21 ] The adhesive properties of hydrogels have been shown to be enhanced by addition of positively charged microgels (MR) into the 3D matrix to increase electrostatic and hydrophobic interactions.
