Lockfast P77 Pipe Sealant

Lockfast P77 Pipe Sealant a yellow, general purpose, fast cure pipe sealant. It is designed for the sealing and locking of metal-fittings and pipes where an instant low pressure seal is needed.  High-viscosity and strong final bond, ideal for coarse-threaded fasteners.  When cured, it can prevent leakage and loosening from vibration and shock, on pipes that can carry liquids or gases.

Directions For Use

1. For optimum performance surfaces should be clean and free of grease.

2. If the material is an inactive metal consider using activator.

3. Shake the product thoroughly before use. Apply several drops to parts to be locked and sealed.

4. Assemble and tighten as required.

5. To prevent the clogging of the nozzle, do not let the tip touch metal surface during application.

Fixture Time vs. Substrate

There may be a difference in fixture speed and strength based on the substrate. As opposed to passive materials such as stainless steel or zinc dichromate, anaerobic adhesives will reach full strength more rapidly with active materials such as mild steel and brass.

For more information on strength of bond and cure time, please see the Lockfast gasketing and pipe sealants technical information sheet.

Disassembly and Clean-up

Remove with standard hand tools. In circumstances where hand tools do not work, use localised heat, disassemble while hot. To remove cured product use a combination of solvent and abrasion such as a wire brush.
