Here is another attempt to answer your question: http://en.wikipedia.org/wiki/Universal_i...
Acrylic Adhesives. Acrylic adhesives can either be water-based (this is also referred to as emulsion or dispersion) or solvent-based. Water-based are slower drying compared to solvent-based systems but generally solvent-based acrylic systems have better resistance to other solvents, chemicals and water.
Today Band-Aid brand adhesive tape is made of acrylic. There are 5 main types of Band-Aids. They are clear tape, cloth, hurt free, waterproof, and paper tape. Johnson and Johnson doesn t use latex on the Band-Aids.. Place egg in water, hold under water until bandage falls off. 6. Repeat for each brand of bandage. Top of page. RESULTS. The original purpose of this experiment was to see which brand of Band-Aid bandage has the most adhesive stick.
