KOPR-KOTE® ARCTIC is the more pumpable or sprayable version of the standard grade KOPR-KOTE, our premier waterwell and HDD drilling compound in the market. It is an unleaded compound containing copper flake, graphite, and other natural extreme pressure and anti-wear additives. KOPR-KOTE® ARCTIC's solids package is formulated to prevent excessive circumferential makeup by increasing the coefficient of friction under compressive forces. As stress levels rise above 50% of yield, the friction factor increases, limiting downhole makeup. Full hydraulic joint efficiency is maintained allowing joint shoulder faces to mate completely without standoff or deformation. This water well drill rod compound offers the best protection in the most severe drilling situations such as higher speeds, higher penetration rates, long horizontal holes or harder formations.
