Consolidants for fossils

There is a consolidant currently on the market produced by Paleobond
which is designed to consolidate fragile fossil specimens using
cyanoacrylates. These polymerise in situ and avoid the problem of
solvent based systems causing the polymer to migrate back towards
the surface as the solvent evaporates.  Does anybody know if there
is information available about the ageing properties of these
cyanoacrylate products. We are concerned about the difficulty of
reversing such a treatment if there were ageing problems in the
future. Any comments gratefully received.
