Abstract: The present invention is directed to amine soluble, or solid copper triazole based wood preservative formulations containing certain types of quaternary ammonium compounds, or nonionic sufactants, and the use of these quaternary ammonium compound-, or nonionic surfactant-containing formulations to pressure treat and preserve wood. The addition of the quaternary ammonium compounds, or nonionic surfactants to the wood preservation treatment solutions allows improved penetration of the copper from the solution into wood and reduces the duration of time required to effectively pressure treat the wood with the preservation composition.

Abstract: The present invention is directed to an apparatus, system, and method for determining the extent of penetration of a preservative in wood. More particularly, the present invention is directed, in certain embodiments, to an apparatus comprising an image sensor capable of detecting a color spectrum of a sample, and a light source; a system comprising an image sensor, a light source, a sample treated with a preservative, an indicator applied to the sample, and a computing device coupled to the image sensor, wherein the computing device is capable of processing an image captured by the image sensor and determining the extent of penetration of the preservative; and methods for using such an apparatus and system to determine the extent of penetration of a preservative in wood by identifying changes in color of wood, wood products, or wood samples.
