Abstract
An iodine/iodide-containing hot melt coatable adhesive is provided. This adhesive is prepared by mixing iodine and an iodide salt, individually or in combination, with solubilizing liquids. The iodine and iodide salt are combined with a pre-adhesive composition in a hot melt mixer, with an iodine/iodide complexing agent being present in the mixture. The mixture is mixed at a temperature from about 130° C. to about 200° C. and sufficiently to form an iodine/iodide-containing hot melt coatable adhesive. Alternatively, the iodide may be generated in situ. The adhesive so prepared may be packaged for coating on a substrate at a later time, or may be immediately coated to form an adhesive composite. Adhesive composites, particularly surgical incise drapes, are provided incorporating this hot melt coatable adhesive.
