Octyl cyanoacrylate

They provide rapid wound closure,[1] are bacteriostatic, and their use is usually painless.

[citation needed] Butyl esters provide a stronger bond, but the glue is rigid.

The octyl ester, while providing weaker bond, is more flexible.

Blends of OCA and n-BCA are available which offer both flexibility and a strong bond.

Heating to higher temperatures causes pyrolysis and depolymerization of the cured glue, producing gaseous products strongly irritating to the lungs and eyes.
