Preserve CA®



Preserve CA – (Copper azole). Copper azole (CA type C) is a wood preservative formulation made of soluble copper and uses organic triazoles (tebuconazole and propiconazole) as the co-biocide to control copper-tolerant fungi.


Preserve® is a family of soluble copper-based preservative solutions for exterior wood products that provides long-term protection from fungal decay and termite attack for a wide variety of residential, commercial and agricultural construction applications. In each Preserve solution, the soluble copper provides most of the protection to the wood, and the co-biocides complete the formulation by adding the protection against the copper-tolerant fungi.  Soluble copper is very effective in penetrating the cells in the wood fiber during the pressure-treatment process, providing for optimum long-term protection.
