The best place to check would be with the Canadian Conservation
Institute.  Jane Down,Conservation Scientist, has been doing
research on various adhesives and is organizing a workshop on
adhesives in palaeontolgy, which includes current information on
cyanoacrylates.

The Society for the Preservation of Natural History Collections
published a wall chart on adhesives in palaeontolgy in 1997.  The
publication can be found at:

Horie in "Materials for Conservation", describes cyanoacrylates as
being sensitive to alkaline conditions, and becoming brittle over
time, especially after being exposed to light.  I wasn't able to
find any written references to a time frame for bond failure.
