This project investigated the technical feasibility and economic benefits of using phenol formaldehyde resins to treat mountain pine beetle-attacked lodgepole pine (Pinus contorta Dougl.) veneers and to produce high-performance, durable engineered wood products. These products have the potential to significantly increase the value recovered from mountain pine beetle wood. A breakthrough resin impregnation technology was developed and a special phenol formaldehyde resin was formulated which significantly simplified the manufacturing process of veneer-based engineered wood products, making it much more cost-effective. The resulting products improved appearance, surface hardness, stiffness, strength, dimensional stability, and decay resistance. They were also environmentally friendly. Because of these features, they can be extensively used for value-added structural and industrial applications and will be able to compete successfully with wood plastic composites and other materials in exterior applications. The new resin impregnation technology is equally applicable to other common Canadian species, such as spruce and aspen. At the current resin price, the application of this technology will result in significant economic gains for Canadian plywood/laminated veneer lumber producers.
