Methyl cyanoacrylate(MCA;also sometimes referred to asα-cyanoacrylateoralpha-cyanoacrylate)[3]is anorganic compoundthat contains severalfunctional groups:amethylester,anitrile,and analkene.It is a colorless liquid with lowviscosity.Its chief use is as the main component ofcyanoacrylate glues.[4][5]It can be encountered under manytrade names.Methyl cyanoacrylate is less commonly encountered thanethyl cyanoacrylate.
It is soluble inacetone,methyl ethyl ketone,nitromethane,anddichloromethane.[6]MCApolymerizesrapidly in presence ofmoisture.
Safety
[edit]Heating the polymer causesdepolymerizationof the cured MCA, producing gaseous products which are a strong irritant to thelungsandeyes. With regard tooccupational exposureto MCA, theNational Institute for Occupational Safety and Healthrecommends workers do not exceed exposures over 2 ppm (8 mg/m3) over an eight-hour workshift, or over 4 ppm (16 mg/m3) over a short-term exposure.[7]
