With over 50 years of experience in the specialty chemicals business, Merichem Chemicals & Refinery Services LLC (MCRS) manufactures high-quality copper naphthenate at its world scale plant in Tuscaloosa, Alabama, USA. Copper naphthenate is available as an oil-borne or water-borne formulation wood preservative that makes sense in the treatment of utility poles as well as for many other uses. It is a logical choice when safety, environment and disposal are considerations.

MCRS CuNap-8™ Wood Preservative is prepared from copper compounds and naphthenic acid. Naphthenic acids occur naturally in certain petroleum fractions.

Every year several million cubic feet of wood are pressure treated with copper naphthenate. This includes thousands of utility poles as well as posts, timbers and lumber.

Copper naphthenate is highly effective against wood-destroying fungi and insects. It is water repellent, leach resistant and has a high degree of fixation to wood fibers.

The U.S. Environmental Protection Agency has classified copper naphthenate as a general use wood preservative because it offers minimal hazard to treaters and users alike. Since copper naphthenate is a non-restricted preservative, it is commonly sold over the counter for use by the general public.
