Description
MM115 PURE Removable Threadlocker is a medium-strength Permabond MM115 PURE anaerobic adhesive for locking metal bolts, nuts, and screws. It cures between close-fitting metal threads, resists loosening from vibration, and allows later disassembly with ordinary tools.
Permabond MM115 PURE Benefits
- Medium-strength removable hold helps service teams take assemblies apart later.
- One-component anaerobic formula cures after assembly between metal threads.
- Thixotropic, non-drip flow helps keep adhesive on the fastener during installation.
- Lubricates threads during assembly and provides controlled off-torque after cure.
- NSF/ANSI 61 certification is listed in the manufacturer technical data sheet.
Use this threadlocker on threaded metal fasteners that may need future service. Apply to clean threads, assemble parts, and allow cure to develop at room temperature. Cure is faster on active metals such as brass and mild steel, while zinc, cadmium, stainless steel, and other passive surfaces may need more time or a suitable activator.
Common Applications for Permabond MM115 PURE
- Locking bolts, nuts, and screws in pumps, equipment, and maintenance assemblies.
- Threadlocking where disassembly with hand tools remains part of the service plan.
- Metal threaded joints in systems where the listed NSF/ANSI 61 status is required.
- Vibration-prone assemblies that need thread friction and gap sealing.
Compatible Metals and Cure Notes
- Steel, brass, zinc, cadmium, and other plated fasteners.
- Close-fitting metal threads with maximum gap up to 0.15 mm or 0.006 in.
- Fasteners that can remain assembled while cure reaches full strength.
- Applications where the specified 250 mL package fits shop or line use.
