When we consolidate the iron artifacts, only we used VM&P Naphtha as solvent of paraloid NAD10. After consolidating the iron artifacts using paraloid NAD10, artifacts were too glossy to exhibit and see. We choose the solvent YK-VMP as solvent of paraloid NAD10 for complementing this defect and examined characterizations of paraloid NAD10 films in each solvent. As a result of evaluation by several surface analysis such as optical microscope, measuring film thickness, adhesive strength, gloss of surface, contact angle, yellowing test and EIS, it is possible to use YK-VMP instead of VM&P Naphtha as solvent of paraloid NAD10, because YK-VMP lowered surface gloss and did not change the effect of consolidation.
