Comparison of copper leaching from alkaline copper quat and copper compound nanosol-based wood preservative treated wood
2024 - IRG/WP 24-20726
To improve the leaching resistance of copper ion-based wood preservatives, copper compound nanosol-based wood preservatives were developed and its copper leaching characteristics were evaluated. Three types of preservatives (DC1, DC2, DC3) were prepared with different crystallinity and dispersant types of copper compound nanosol, and the copper concentration was adjusted to be the same as that of ...

A new wood preservative system based on basic copper compound nanosols
2024 - IRG/WP 24-20728
A bottom-up process was established to synthesize insoluble basic copper compound nanoparticles and simultaneously form a stable nanosol by dropping a neutralizing agent solution into an aqueous solution of a copper compound to which an appropriate dispersant system was added. The main ingredient of MCA (Micronized Copper Azole), the leading copper-based wood preservative in the current world mark...
