Pressure-sensitive adhesive

A self-stick adhesive commonly used on tapes, labels, and stamps, characterized by bonding to another surface with slight pressure at room temperature. Such adhesives are distinct from other adhesives in that they do not require solvent evaporation or a chemical reaction in order to bond. They have been applied to cloth, paper, film, foil, and foam substrates. They may be made from natural rubber, butyl rubber, styrene-butadiene rubber, nitrile rubber, acrylic, polyvinylalkyl ether, or silicone formulations. They commonly contain additives such as tackifiers, plasticizers, fillers, and antioxidants. They are used in the industrial and commercial market in the form of adhesive tapes and films directed toward packaging, mounting and fastening, masking, and electrical and surgical applications.
