In her diploma theses, written 2001 at the Fachhochschule Koln,
Germany, Ebba Krieger writes about the penetration pattern of
synthetic resins into insect-ridden wood. A short article on the
subject was published in "Zeitschrift fr Kunsttechnologie und
Konservierung" 17. Jahrgang 2003, Heft 2.It may be interesting for
you to read this article. Paraloid B-72 in Toluene (25% and 30%) as
well as Plexigum PQ 611in Benzine 100-140 (25%)are mentioned as
being well suited to penetrate sufficiently deep as well as to give
sufficient stability to the sample blocks of insect damaged wood.
