Ethyl Cyanoacrylate

Ethyl cyanoacrylate (ECA), a cyanoacrylate ester, is an ethyl ester of 2-cyano-2-propenoic acid. It is a colorless liquid with low viscosity and a faint sweet smell in pure form. It is the main component of cyanoacrylate glues and can be encountered under many trade names. "Super glue" is believed to be ECA. The makers of "Krazy Glue" state on their website, "The chemical name for Krazy Glue is ethyl cyanoacrylate." Mercury Adhesives is an example of an American-made ECA. It is soluble in acetone, methyl ethyl ketone, nitromethane, and methylene chloride. ECA polymerizes rapidly in the presence of moisture.
