The effect of various solvents and solvent mixtures was tested on a selection of epoxy resin adhesives. The selection was based on the resistance to yellowing of the resins. Quantitative data were obtained by the measurement of the two-dimensional swelling of the free film samples. The methods of testing and the results obtained are discussed. A list of powerful solvents with an indication of their relative solubilizing power for the adhesive are provided. Since each of the resins tested reacted in different ways to the solvents, some new recommendations regarding the use of epoxy resins in conservation are described. Adhesives included Ablebond 342, Araldite 502/HY 956, Epo-Tek 301-1, Epo-Tek 301-2, and Epoxyglass.
