摘要：

Some of the ways to solve major deficiencies of wood-plastic composites (WPC) are discussed. The technology consists of performing a surface modification on the WPC followed by application of an appropriate coating. WPC's can be colored and glossy, with 30 years projected durability by applying a high performance coating, such as the aliphatic polyurethane systems used on automobiles. Appropriate coatings can provide outstanding scratch and mar resistance, as well as provide a surface that is easy to clean. Appropriate coatings can seal the WPC to prevent moisture absorption, mold growth, and physical property reduction. Using coating systems can also enable homeowners to repaint their WPC to match new decoration schemes. The plastics industry has developed several useful methods for surface-modifying low energy plastics to enable adherence. These processes oxidize the surface, creating high surface energies.
