Bringing Better Ideas to the Surface through Science and Innovation

In the 3M Industrial Adhesives and Tapes Division, they apply the science of adhesion to deliver innovative solutions that improve the design and manufacturing processes of companies around the world. In the end, their technologies help customers like you deliver competitive products to the market faster and more efficiently.

Understanding Instant Adhesives

Instant adhesives are cyanoacrylate based formulas that are strong, fast-acting glues used in industrial 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 right from the container and rapidly reach handling strength at room temperature. Commonly referred to as a super glue, a single drop per square inch can bond many plastics, rubbers, metals, wood and more. An instant adhesive from 3M set a Guinness World Record in 2012 for the strongest glue by lifting an 8.1 metric ton forklift in the air for one hour.
