Abstract

This paper reports on preliminary investigation of the properties of randomly oriented strandboard which had waterborne or powdered copper naphthenate incorporated into the board during manufacture. When compared to zinc borate-treated controls, the mechanical properties of strandboard were not adversely affected by treatment with either form of copper naphthenate. In general, values for mechanical properties followed the trend untreated controls > waterborne CuN = powdered CuN > ZnB. Water absorption and dimensional properties followed a similar trend. This preliminary study suggests that CuN is a viable alternative treatment for engineered wood composites.
