Kopr-Kote® Drill Collar & Tool Joint Compound
A premium quality, unleaded compound containing copper flake, graphite, and other natural extreme pressure and anti-wear additives. KOPR-KOTE’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.
For optimum performance on API drill string connections, KOPR-KOTE® should be utilized with the thread recommended torque by multiplying the torque value by 1.15 or by contacting the drill pipe and connection manufacturer. Friction factors for KOPR-KOTE were developed using full scale API tool Joint connections. For a 1.0 friction factor use Kopr EXT FF 1.0.
For invert or high-pH muds, use Jet-Lube® EXTREME®. For wedge-type thread connections, use NCS-30® ECF™ for best thread-wear protection.
