ETHYL 2-CYANOACRYLATE

Description

Ethyl cyanoacrylate is contained in instant glues for metal, glass, rubber, plastics, textiles, tissues and nails. It polymerizes almost instantaneously in air at room temperature and bonds immediately and strongly to surface keratin. Beauticians are exposed to contact dermatitis from nail glues.

Description

Ethyl 2-cyanoacrylate is a liquid that you’ve probably used around the house. Because of its conjugated unsaturated groups, it polymerizes easily. It is prepared by condensing ethyl 2-cyanoacetate with formaldehyde, followed by thermal decomposition of the resulting polymer.
Ethyl 2-cyanoacrylate and other less common 2-cyanoacrylate esters are the active ingredients in commercial superglues or instant glues. Some of these products contain additives such as fumed silica to make them more viscous or rubber to make them more impact resistant.
Cyanoacrylates were discovered serendipitously during World War II when scientists at B.F. Goodrich (located in Akron, OH at the time) sought suitable clear plastics for gun sights. Chemist Harry Coover Jr. and co-workers found that the esters auto-polymerized and stuck to everything in sight. Because of the wartime urgency for other materials, cyanoacrylates were abandoned until 1951, when Coover, then at Eastman Chemical (Eastport, TN), and colleague Fred Joyner “rediscovered” it. The first commercial glue appeared in 1958.
Ethyl 2-cyanoacrylate and its cousins polymerize instantly in water. The small amount of moisture in air is enough to initiate polymerization. The polymer forms within a matter of minutes, creating a bond that is often stronger than the materials it joins.
Despite its strength, the polymer can be removed by soaking it in acetone or mild acids. Household products such as nail polish remover or lemon juice will do the trick.

The Uses of ETHYL 2-CYANOACRYLATE

Ethyl cyanoacrylate is an acrylate compound used in instant glues to mend broken nails and to adhere glue-impregnated silk or linen to the nail plate, which is then filed to shape the nail; in medicine to glue tissues and skin cracks; to attach hair and to glue shoes, plastics, and many other materials.

The Uses of ETHYL 2-CYANOACRYLATE

ECA can be used as a tissue adhesive for potential applications in cardiovascular and pulmonary surgeries. It can also be mixed with hydrophobic silica nanoparticles for the designing of cotton fabrics for medical applications.
