摘要

An aqueous wood-injectable particulate-based wood preservative comprising: 1) dispersants in an amount sufficient to maintain biocidal particles in a stable slurry; 2) injectable sub-micron biocidal particles comprising a solid phase of at least one of a sparingly soluble organic biocide, a sparingly soluble copper salt, copper(I)oxide, a sparingly soluble zinc salt, zinc oxide; a sparingly soluble nickel salt; and a sparingly soluble tin salt, wherein less than 2% by weight of the biocidal particles have an average diameter greater than 1 micron, and at least 20% by weight of the biocidal particles have an average diameter greater than 0.08 microns; and 3) at least one pigment particle or dye in an amount sufficient to impart a discernable color or hue to the wood, when compared to wood treated with the same particulate system but without the pigment.
