Why Does Super Glue Stick to Almost Any Surface?

With the accidental discovery of Super Glue, Dr. Harry Coover appeared on the television show, "I've Got a Secret," and with a single drop of Super Glue, lifted the host off the ground. Binding wounds during the Vietnam War, Super Glue saved thousands of lives and became a household name, notes the Lemelson MIT Program.

Significance

• Super Glue's binding capacity comes from the chemical agent, methyl cyanoacrylate. Once the glue cures, it transforms from a liquid to a solid when introduced to water, alcohol or blood. The chemical makeup of cyanoacrylates adhere both ends of a glued object, binding surfaces like knitted cloth. According to the Chemistry Division at UCLA, the binding process of Super Glue is known as an anionic chain polymerization reaction. Most objects have a thin layer of moisture on their surface, even in the form of condensation. Accidental spills of Super Glue absorb the liquid, resulting in chemical bonding. Users will often glue a finger or two together because of Super Glue's binding capability, describes the Super Glue Corporation.

Function

• More effective than sutures for wound healing in the battlefield, Super Glue is a powerful tool for laceration repair. Dental procedures use cyanoacylates like Super glue to fix fillings and repair dental fixtures. According to the Lemelson MIT Program, cyanoacylates, similar to Super Glue, are used during surgery to reconnect veins and arteries and seal bleeding ulcers. Super Glue binds fragile fossil specimens at archaeological digs so that they can be moved safely. Forensic personnel apply this glue to lift and identify fingerprints. With all these noble uses, it is not surprising that Super Glue also repairs a variety of everyday items.

Safety

• Because Super Glue will stick to almost any surface, knowing how to handle and remove this adhesive tool is essential. The Super Glue Corporation recommends using acetone, Super Glue's one weakness, if fingers become glued together or objects are stuck to the skin. The Corporation cautions users to remove any object slowly to avoid tearing the skin. Acetone will discolor fabric and damage laminated counter tops, so it is necessary to protect the work area from exposure to this glue. Users should contact their doctor if sensitive areas such as lips or eyes become exposed to Super Glue.
