  • Ethyl cyanoacrylate

    serch.it?q=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 presence of moisture.

    Chemical structure of methyl cyanoacrylateCyanoacrylates are a family of strong fast-acting adhesives with industrial, medical, and household uses. Cyanoacrylate adhesives have a short shelf life if not used, about one year from manufacture if unopened, and one month once opened. They have some minor toxicity. Cyanoacrylates include methyl 2-cyanoacrylate (MCA), ethyl 2-cyanoacrylate (ECA, commonly sold under trade names such as "Super Glue" and "Krazy Glue", or Toagosei), n-butyl cyanoacrylate (n-BCA), octyl cyanoacrylate and 2-octyl cyanoacrylate (used in medical, veterinary and first aid applications). Octyl cyanoacrylate was developed to address toxicity concerns and to reduce skin irritation and allergic response. Cyanoacrylate adhesives are sometimes known generically as instant glues, power glues or superglues. The abbreviation "CA" is commonly used for industrial grade cyanoacrylate.
