A Note On Assessing The Deterioration Of Thin Wood Veneers During Weathering
Keywords:Radiata pine, weathering, weight loss, lignin, polysaccharides, solubility
AbstractWeight loss was used to assess the deterioration of thin wood veneers during weathering. Significant weight losses resulting from degradation of the lignocellulosic matrix rather than from losses of water-soluble extractives occurred during exposure.
