ADHESIVE QUALITIES OF CONSOLIDANTS FOR DETERIORATED WOOD

TOMOYASU SAKUNO, & ARNO P. SCHNIEWIND



5 CONCLUSIONS

ACRYLOID B72, Butvar B98, and AYAT solutions suitable for consolidation were investigated for their adhesive qualities and compared to a polyvinyl acetate emulsion adhesive. The most important factor governing adhesive strength was found to be the choice of solvent, since polar solvents gave much better results than nonpolar ones. Even the best consolidant solutions did not give adhesive bonds as strong as those afforded by the PVA emulsion adhesive. However, the basic adhesive qualities of all three resins were judged excellent if a suitable solvent was used. The nature and condition of the wood adherend were also found to be important factors in the bond strength that could be obtained.
