We examined characterizations of Paraloid B72 films when it dissolved in four different solvents-ace-tone, MEK, toluene and xylene. The surface before and after coating were observed by optical microscope and AFM.films. We also tested adhesive strength of films by scratch tester and durability of films by performing yellowing test.The result was that xylene has better coating property than other solvents. Because 10% Paraloid B72 in xylene filmis even, non-mottled, thin, stabilized in yellowish and has proper hydrophobic, we confirmed xylene is good solventfor bronze artifact conservation. However, other tests will need for finding appropriate concentration of ParaloidB72.
