초록

Paraloid B-72 of acrylic resins has been widely used as consolidant for bronze artifacts conservation. In previous study, xylene was appropriate for paraloid B-72 when bronze artifacts consolidated. In this study, we compared the coating properties of paraloid B-72 in various concentration levels. The surface before and after coating were observed by optical microscope and AFM. Thickness and adhesive strength of films were tested. For testing coating stability, we performed yellowing test and EIS. After these experiments, we concluded 15wt% paraloid B-72 was adequate concentration for bronze artifacts conservation when paraloid B-72 used in xylene as solvent. Because 15wt% paraloid B-72 has the lowest polarity and high hydrophobic.
