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 invert or high-pH muds, use Jet-Lube® EXTREME®. For wedge-type thread connections, use NCS-30® ECF™ for best thread-wear protection.
Benefits:
- Aluminum-complex grease base protects against rust and corrosion
