Chemola™ ThredOn™ Black Gold

Copper Compound for Tubing and Casing

Chemola™ ThredOn™ Black Gold is an environmentally friendly tubing and casing compound used on all threaded connections. Due to the high percentage of solids suspended in this compound, it can also be used as a high temperature thread sealant. Black Gold contains Chemola™’s exclusive Copper+ additives package with over 50% solids for superior sealing ability and ease of break-out. Black Gold will prevent galling or damage to threads while ensuring a positive seal. It is easy to apply to dry or wet threads.
