    cyanoacrylate. 

    OTHER ACRYLATES: Many other efforts in wood impregnation exist.
    Daniel Deitch, a Baroque woodwind maker in San Francisco, has
    utilized cyanoacrylate impregnation for wood stabilization. MMA has
    the structure H2C=C(CH3)COOCH3, while a typical cyanoacrylate has a
    structure H2C=C(CN)COOCH3. They differ by the substitution of a -CN
    group for a -CH3. This substitution makes it easier for the material
    to polymerize into long carbon chains, much like a zipper closes. The
    cyanoacrylates are used as rapid setting "glues". Deitch swabs out
    the finished bores with the cyanoacrylates, lets the material
    polymerize, and then finishes the interior surface. Deitch also
    reports that he has been pleased with a technique for finishing the
    exterior learned from Rod Cameron, a flutemaker from Mendocino, CA. A
    few drops of the cyanoacrylate are added to linseed oil, and the
    mixture applied as a hardening finish to the exterior. The
    cyanoacrylate accelerates the hardening of the mixture. Do not be
    concerned about the presence of the -CN group in the molecule. It is
    an organic nitrile or cyanide, not an inorganic cyanide. The latter
    are toxic, but the organic -CN is not. Some artisans find the
    cyanoacrylic bore finish beads water excessively. 

Hopefully this eases your worries, it did mine! Marta
