As a zinc-free, thread locking compound, Liquid-O-Ring 252 Liqui-Lok Zinc-Free is specially formulated to replace the welding of casing joints and threaded connections. This two-part epoxy compound is easily mixed under wide range of temperatures due to its workable consistency.Liquid-O-Ring 252 Liqui-Lok Zinc-Free is unaffected by vibration, pounding, or expansion due to temperature changes. It withstands high break-out torque and provides a leakproof seal.
\nBENEFITS
\n\u203b Zinc-free
\n\u203b Environmentally friendly in cured form
\n\u203b\u00a0Mixes easily
\n\u203b Workable consistency in excess of one hour
\n\u203b Water resistant
\n\u203b Oxidation resistant
\n\u203b Withstands high break-out torque
\n\u203b Provides a leak-proof seal and strong permanent bond
\n\u203b Self lubricating
\n\u203b Unaffected by vibration, pounding or temperature
\n\u203b Excellent adhesion
\nAPPLICATION
\n1. Thoroughly clean male and female threads to remove all thread dope, oil, and grease.
\n2. Dry threads completely prior to application of 252 Liqui-Lok Zinc-Free.
\n3. Thoroughly mix contents of can; add entire bottle of hardener and continue mixing until
\ncompletely uniform.
\n4. When used in conjunction with float equipment, apply 252 Liqui-Lok Zinc-Free to male threads
\nusing a putty knife or spatula.
\n5. Make up joints final torque without delay.
\nNOTE
\nSetting 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\u00b0F (121\u00b0C) or increased by lowering the temperature. The cure seal may be broken out by heating the joint to >550\u00b0F (287.8\u00b0C). Wet joints
\nor high moisture conditions may affect curing ability.
