Abstract
In this study, the stability of the adhesive was determined through the Oddy Test that is Verification Test for potential damage by various materials. And to find the factor causing the corrosion of the metal samples, the adhesives and coatings those are usually used in the metal preservation process were selected and treated on the samples. Six kinds of adhesives and four kinds of metal specimens Fe, Pb, Cu, Ag were used. As results, the weight change showed high increasement in the rate of weight change 29.87% of Fe sample. The chromaticity measurement showed the high change value of the Cellulose-based adhesive. In case of the VOCs test from adhesive by using GC-MS, Acetic acid was detected from all six kinds of the adhesives. Compared to cellulose-based adhesives and the other adhesives, the amount of VOCs per 1mg concentration is higher than 900 times and was detected small amount of Formic acid. This is assumed to be facilitated by acid impurities and the light. This reaction was considered as the result of reducing a large amount of molecular and of generating a large amount of Nox. And thus the reacted sulfur changes was considered as the factor for causing corrosion.
