Panels from laminated phenol-formaldehyde resin (PF) impregnated and compressed wood (Compreg) with top veneers from European species of beech, maple and white birch were prepared, each without or coated with resin pre-impregnated overlay papers. To clarify the outdoor resistance of Compreg surfaces, long-term artificial weathering experiments were performed. Weather-related color changes, gloss retention and microscopic and surface topographical surface alterations were examined. It has been observed that the application of PF impregnated paper overlays and combinations of them with melamine formaldehyde resin (MF) treated films significantly improved the weather resistance of Compreg surfaces. The extent of UV and moisture-induced surface damages of Compreg has been shown to also be dependent on the veneer types used as surface top layer. Highest surface and color stabilization against weather was achieved providing Compreg with top veneers from maple combined with PF overlays or applying both MF and PF impregnated overlay films as surface finish.

制备了由层压酚醛树脂（PF）浸渍和压缩木材（Compreg）以及来自欧洲的山毛榉，枫木和白桦树种的单板制成的面板，每个面板都没有或未涂有树脂预浸渍的覆盖纸。为了弄清Compreg表面的室外电阻，进行了长期的人工耐候性试验。检查与天气有关的颜色变化，光泽保持力以及微观和表面形貌的表面变化。已经观察到，PF浸渍纸覆盖层以及它们与三聚氰胺甲醛树脂（MF）处理过的薄膜的组合使用显着改善了Compreg表面的耐候性。已经证明，紫外线和湿气对Compreg造成的表面损伤的程度还取决于用作表面顶层的贴面类型。
