  • 현재 철제유물 강화처리 시 사용하는 아크릴계 수지인 Parabid NAD10은 용제로 VM&P Naphtha만을 사용하고 있다. 그러나 이를 사용하여 강화처리 할 경우 코팅 후의 광택이 높아 전시 및 관람에 불편함을 준다는 문제가 제기되고 있다. 이러한 단점 보완을 위해 대체 용제로 YK-VMP를 선정하여 각 용제별 코팅 특성을 비교 분석하였다. 표면관찰, 박막 두께, 접착력, 접촉각 및 표면에너지, 광택도, 황변실험, EIS 평가 등의 일련의 분석을 통해 용제별 코팅 특성을 비교한 결과, 기존의 VM&P Naphtha를 대신하여 YK-VMP를 사용하여도 강화처리 효과에는 큰 영향을 주지 않으면서도 광택을 더 낮춰주는 효과가 나타나는 것을 확인하였다.

  • Objectives: This study was conducted to identify the ingredients used in ten consumer product categories and determine hazardous substances among these ingredients. Methods: A total of 542 commercial products in ten consumer product categories were selected. The consumer products were sticker removers, washing machine cleaners, multi-purpose cleaners, mold removers, glass cleaners, chlorinated sanitizers, air conditioner cleaners, disposal cleaners, drain cleaners and disinfectant sprays. The company list was complied from governmental records and a market survey. The respective companies were contacted for a list of ingredients found in the 542 products. Results: The corresponding companies listed 163 ingredients. According to European Union (EU) Directive 67/548/EEC, 38 of the 163 ingredients were classified as dangerous substances. Among these substances, 28 ingredients were hazardous to the skin, 15 were hazardous to the eye, and nine were hazardous if inhaled. Three ingredients were classified as CMR (carcinogenic, mutagenic or toxic for reproduction) substances: liquefied petroleum gases (LPG) with carcinogenicity and mutagenicity, and VM&P naphtha and ligroine with carcinogenicity. Conclusion: Various chemicals, including hazardous substances, were used in consumer products. Risk assessment of consumer products is required in order to protect the population from health risks.
