Ethyl cyanoacrylate (ECA), a cyanoacrylate ester, is an ethyl ester of 2-cyano-2-propenoic acid. It is a colorless liquid with low viscosity. It is the main component of cyanoacrylate glues and can be encountered under many trade names. Super glue and Krazy glue are believed to be virtually 100% ECA.[1] It is soluble in acetone, methyl ethyl ketone, nitromethane, and methylene chloride.[2] ECA polymerizes rapidly in presence of moisture.
