Abstract
Manicure is used for sealing of the cover glass on slide specimen. However, manicure should be avoided to use in classroom, because it not only relatively takes time for drying but also has irritating odor of organic solvent such as acetone and butyl acetate. Ultraviolet curable resins, known as industrial materials for sealing and bonding, is used to coat and decor surface of nail instead of manicure. Ultraviolet curable resins are liquid materials that are polymerized and cured in a few minutes by irradiated with spectral band of UVA (315-400 nm). In this experiment, some ultraviolet curable resins were evaluated about the evaporation restraint ability by using methylene blue solution. It was found that they clearly prevented water evaporation better than manicure under incubation at 20℃ for 2 weeks. Thus, ultraviolet curable resins would replace manicure for the slide glass specimen sealing in school.
