Impact glue

Impact glue, contact glue, contact cement, or neoprene glue is a type of solvent-based adhesive which may be used to bond materials such as plastics, laminates, and metal or wood veneers. The term "contact glue" come from the practice of applying adhesive to both surfaces to be bonded; the surfaces are joined once the solvent in the adhesive evaporates, leaving a bond with high shear resistance. Contact adhesives do not exclusively designate neoprene adhesives; all adhesives characterized by high instant adhesion may be considered contact adhesives, but the most common among them are solutions of neoprene or rubber.
