250 Liqui-Lok Thread Locking Compound is a two part epoxy compound used to replace the welding of casing joints and threaded connections. 250 Liqui-Lok is unaffected by vibration, pounding, or expansion due to temperature changes. It withstands high break-out torque and provides a leakproof seal. 250 Liqui-Lok is easily mixed under varying temperatures due to its workable consistency in excess of one hour.
BENEFITS：
▪ Friction factor of 1.5
▪ Mixes easily
▪ Workable consistency in excess of one hour
▪ Water resistant
▪ Oxidation resistant
▪ Withstands high breakout torque
▪ Provides a leakproof seal and strong permanent bond
▪ Self lubricating
▪ Unaffected by vibration and pounding
▪ Excellent adhesion
APPLICATION：
▪ Thoroughly clean male and female threads to remove all thread dope, oil, and grease.
▪.Dry threads completely prior to application of Liqui-Lok.
▪.Thoroughly mix contents of can; add entire bottle of hardener and continue mixing until completely uniform.
▪ When used in conjunction with fl oat equipment, apply Liqui-Lok to male threads using a putty knife or spatula.
▪ Make up joints final torque without delay.
NOTE：
Setting action begins immediately after addition of the hardener. The mixture will remain in a workable consistency from 45 minutes to 2 hours under average conditions. Curing time may be reduced by elevating the temperature up to 250°F (121°C) or increased by lowering the temperature. The cure seal may be broken out by heating the joint to >450°F (232°C). Wet joints or high moisture conditions may affect curing ability.
