Instant adhesives are cyanoacrylate based formulas that are strong, fast-acting glues used in industrial, automotive, and household applications. In general, they are an acrylic resin that rapidly polymerizes in the presence of moisture, forming long, strong chains, joining the bonded surfaces together. Cyanoacrylate adhesives should be applied thinly, with pressure put on the bond for a few seconds, to ensure that the reaction proceeds rapidly and a strong bond is formed within a reasonable time.

3M instant adhesives apply directly from the container and rapidly reach handling strength at room temperature. Commonly referred to as super glue, a single drop per square inch can bond many plastics, rubbers, metals, wood and more.
