Abstract
This invention discloses a non-water dilutable remedial wood preservative containing 1/2 to 10 parts copper derived from amine-inorganic copper complexes, combined with sodium borate or sodium fluoride, or a combination thereof, in a ratio of 2 to 120 parts of the sodium salt for each part of copper in the preservative. This invention also discloses the improvement in copper penetration into the wood which occurs when the amine-inorganic copper complexes are combined with sodium borate and/or sodium fluoride, and a novel method of thickening these compositions.
