Removable film forming gel compositions and methods for their application

Film forming gel compositions, useful in creating conformable and flexible gel bandages, can be formulate from a film-forming polymer, a tackifier, and a volatile solvent. The film forming gels can also include antiseptics, cationic polymer coagulants, fillers, and other additives. The gel compositions form relatively thick films when dried on tissue, and can exhibit enhanced breathability to promote wound healing.
