Abstract
The use of UV curing applications has become widespread with the development of technology today. The advantages of these UV curable systems also support customers' various usage characteristics (volatile organic compound, resistance, etc.). These applications are preferred in terms of many sectors, and one of the application areas is wood material surfaces. In this study, changes in the surfaces of Taurus cedar (Cedrus libani A. Rich) wood surfaces, which are exposed to an artificial aging environment with UV-B 313 lamps, on materials with UV curing parquet varnishes were investigated according to industrial applications. According to the research results; in aging applications, brightness (parallel and perpendicular to the fibers at 20o, 60o, and 85o) values and luminance (L*) values decreased, while red (a*) and yellow (b*) color tone values increased. In addition, the pendulum hardness values decreased after aging in the 3-coat application and increased in the 5-coat application. After 504 hours of aging, the total color difference (∆E*) values in both varnish types gave the “different color” criterion. As a result, it can be said that Taurus cedar can be used in the UV system parquet industry when compared with the studies in the literature.
