JET-LOK® II is a two-part epoxy with metallic fillers that can be used to permanently lock threaded connections under normal operation conditions. It is designed for use on all threaded joints or fasteners where an exceptionally strong and durable bond is required. It is especially useful on drilling tools, casing, and other tubulars where the effective prevention of joint loosening is required. The catalyst is emptied into the can containing the base epoxy resin, where the two thoroughly mixed. The applicator is used to completely cover the male threads with the mixture and the joint is then coupled. Complete cure for both occurs in 24 hours. The cure time can be reduced by elevating the temperature up to 250°F (121°C).
