Abstract
An adhesive dressing comprising a conformable, elastomeric backing layer comprising a first side and a second side, a pressure-sensitive adhesive disposed on the first side, and a topcoat applied to the second side, wherein the topcoat comprises a friction-reducing surface finish, wherein the coefficient of function of the topcoat is equal to or less than 0.6 as measured by ASTM 1894-95.
Claims29
An adhesive dressing, comprising
- a conformable, elastomeric backing layer comprising a first side and a second side opposite the first side;
- a pressure-sensitive adhesive layer disposed on the first side of the backing layer;
- and,
- a topcoat having an inner surface and an outer surface, wherein the inner surface is disposed on the second side of the backing layer and wherein the outer surface comprises a friction-reducing surface finish having a coefficient of friction equal to or less than about 0.6 as measured by ASTM 1894-95.
The adhesive dressing of claim 13, wherein the outer surface of the topcoat is textured.
A method of making an adhesive dressing, comprising
- forming a backing layer;
- disposing a topcoat having an inner surface and an outer surface onto a first side of the backing layer, wherein the inner surface is disposed on the backing layer;
- and,
- wherein the outer surface comprises a friction-reducing surface finish having a coefficient of friction equal to or less than about 0.6 as measured by ASTM 1894-95.
A method of making an adhesive dressing, comprising
- disposing a curable topcoat composition having an inner surface and an outer surface onto a first side of a backing layer, wherein the inner surface is disposed on the first side of the backing layer;
- texturing at least a portion of the outer surface of the topcoat composition;
- and
- curing the curable topcoat composition, to provide at least a portion of the outer surface with a friction-reducing surface finish having a coefficient of friction equal to or less than about 0.6 as measured by ASTM 1894-95.
