THE QUANTITATIVE TESTING AND COMPARISONS OF PEEL AND LAP/SHEAR FOR LASCAUX 360 H.V. AND BEVA 371Kenneth B. Katz
ABSTRACT—The experiment involved the quantitative testing of bond strengths produced by the reactivation of dried adhesive, Lascaux 360 H. V. and Beva 371. Reactivation was by heat or solvent activation (xylene). These reactivation methods were chosen because of the apparent new interest in lower temperature linings and linings that can be easily reversed, mechanically. Bond strengths were also tested and compared to canvases that were sized with 10% B 72. Results indicate that sizing the original canvas can increase the peel strengths significantly during heat activation. It also appears that solvent activation of the both adhesives produce stronger peel strengths than the heat activated samples. The results corroborate empirical tests and are meant only as broad guidelines for using these adhesives in the ways tested.
