CHROMATED COPPER ARSENATE WITH CLIMBING ADDITIVE

Koppers developed an oil-based emulsion climbing additive for CCA treated wood utility poles to improve their climbability characteristics. CCA treated poles with the Climbing Additive, based on testing conducted at Louisiana State University (LSU) and linemen climbing trials show that gaff penetration and climbing confidence is similar to oil-based treated poles such as; oil pentachlorophenol (penta).

LSU SUMMARY OF RESULTS

A review of the gaff hardness and pilodyn penetration data obtained from this testing showed that the Koppers oil-based emulsion, at a loading of 1.02 pcf, provided a pole surface hardness that was comparable to other CCA treated poles with a similar oil-based climbing additive at a loading of 1.20 pcf. The surface hardness of the pine poles treated with the Koppers oil-based emulsion was also slightly improved over that of the oil-based pentachlorophenol treated Southern Pine pole sections.

  • CCA with Climbing Additive provides similar and/or improved performance vs. penta
  • Better climbability (gaffing) and pole softness vs. penta

Koppers has also developed a brown color system (similar to the color of an oil-based pentachlorophenol treated pole) for a utility pole treated with CCA with climbing additive

  • Use of colorants provide CCA with Climbing Additive a brownish appearance similar to penta
