what is the sticky stuff on band aids
Adhesive bandage The adhesive sheet is usually a woven fabric, plastic (PVC, polyethylene or polyurethane), or latex strip. It may or may not be waterproof; if it is airtight, the bandaid is an occlusive dressing. The adhesive is commonly an acrylate, including methacrylates and epoxy diacrylates (which are also known as vinyl resins).[2]
Harry Coover In 1942, while searching for materials to make clear plastic gun sights, Coover and his team at Eastman Kodak examined cyanoacrylates, a material that was used during both World Wars (1914-1918; 1939-1945) as an alternative to stitches on large cuts and wounds,[citation needed] rejecting them as too sticky. Nine years later, Coover was overseeing Kodak chemists investigating heat-resistant polymers for jet canopies when cyanoacrylates were once again tested and proved too sticky. That time around, however, Coover recognized that he had discovered a unique adhesive. In 1958, the adhesive, marketed by Kodak as Super Glue, was introduced for sale.[4]
