  • The tropical woods Apuleia leiocarpa, Couratari stellata, Mezilaurus itauba and Simarouba amara were selected to examine the effect of the presence of the extractives in the color variation and in the photodecomposition process of their surfaces. Samples with and without extractives were submitted to cycles of ultraviolet radiation (350 nm) and immersion in water until totalizing 2,000 hours of irradiation and 400 hours of water leaching. Changings in the natural wood colors were monitored by… CONTINUE READING
