DETERMINATION OF THE COLOR STABILITY OF AN ENVIRONMENTALLY-FRIENDLY WOOD STAIN DERIVED FROM OLEANDER (NERIUM OLEANDER L.) LEAVE EXTRACTS UNDER UV EXPOSURE
Özet
This study was conducted to develop an environmentally friendly wood stain derived from oleander (Nerium oleander L.) and determine the color stability of this stain to UV light irradiation. Wood stains derived from oleander were prepared from aqueous solution with alum and iron mordant mixtures. Yellow Scots pine (Pinus sylvestris L.) and Turkish oriental beech (Fagus orientalis Lipsky) wood specimens were used for the study. After treatment with the stain, wood panels were exposed to UV light irradiation for periods of 500, 1000 and 1500 hours. Results showed that oleander extract as a stain for wood provided some stability to color change after UV irradiation.
