CU-BOR Wood Preservative
Copper and Boron:
These two elements are combined in CU-BOR to provide a new generation of wood preservative which deeply
penetrates and protects wood against insect and fungal attack without pressure
treatment.
Field testing of CU-BOR conducted at the
USDA Forest Products Laboratory near Saucier,
After 3.5 years both the
copper and the borax in CU-BOR have penetrated to the core of
the post at groundline in high concentrations after being applied in a
bandage treatment at 1/4 inch thick.

CU-BOR utilizes copper and boron as it is found in Copper
Hydroxide and Sodium Tetraborate Decahydrate, also known as Borax. These forms are low in toxicity, making CU-BOR
very safe to use and apply when compared with other alternative wood
preservatives. Man has used products containing these elements, copper and
boron, safely for hundreds of years.
Common copper pennies, jewelry, and copper mixing bowls are part of
everyday life. Borax laundry fresheners
and boric acid eye-wash solutions testify to boron’s low toxicity to man.
Simple organisms, (such as termites and
basidiomycete decay fungi), unlike mammals, are extremely vulnerable to contact
with these two elements. AWPA standard
C-4 shows how little copper is needed be to protect wood in ground contact.
