| Section2 = }} Octyl cyanoacrylate (OCA), a cyanoacrylate ester, is an octyl ester of 2-cyano-2-propenoic acid. It is a clear colorless liquid with a sharp, irritating odor. Its chief use is as the main component of medical cyanoacrylate glues. In medical and veterinary applications, octyl cyanoacrylate, ''n''-butyl cyanoacrylate and isobutyl cyanoacrylate are commonly used. They provide rapid wound closure, are bacteriostatic, and their use is usually painless. Butyl esters provide a stronger bond, but the glue is rigid. The octyl ester, while providing weaker bond, is more flexible. Blends of octyl cyanoacrylate and ''n''-butyl cyanoacrylate are available which offer both flexibility and a strong bond. It polymerizes rapidly in presence of moisture. Heating to higher temperatures causes pyrolysis and depolymerization of the cured glue, producing gaseous products strongly irritating to lungs and eyes. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Octyl cyanoacrylate」の詳細全文を読む スポンサード リンク
