Permabond AA001150001L0101, MM115 Anaerobic Threadlocker, 1 Liter Bottle, Case of 10
Permabond MM115 is a blue, medium-strength anaerobic threadlocker and sealant for metal bolts, nuts and screws that may require disassembly for service and maintenance. Its thixotropic formulation resists dripping, while its medium cured strength allows disassembly with ordinary tools. This listing supplies ten 1-liter bottles, SKU AA001150001L0101.
Best Uses / Applications
- Locking metal fasteners against vibration loosening in machinery and equipment manufacturing.

- Valve fastener assemblies: Permabond's valve guide identifies MM115 and A1042 for stuffing-box and bonnet bolts; select the grade for the specific joint.
- EV-charging equipment metal-part assemblies that may need later repair or disassembly, as discussed in Permabond's application guide.
- Industrial maintenance using steel, cadmium, zinc and other plated metal fasteners.
Key Features
- Medium strength with controlled off-torque.
- Prevents vibration loosening and provides corrosion protection within threads.
- Non-drip, thixotropic viscosity.
- UV fluorescence for detecting adhesive presence.
- Lubricates threads for easier assembly.
- Room-temperature cure and 100% solids formulation.

Values are typical manufacturer data, not guaranteed assembly specifications. Cure varies with substrate, temperature and gap. Copper alloys accelerate cure; passivated or oxidized surfaces such as stainless steel can slow it. Permabond identifies A905, ASC10 or heat as options to reduce cure time.
MM115 vs. LM113: Medium or Low Strength?
| Selection point | MM115 | LM113 |

Surface Preparation & Application
Permabond states that MM115 tolerates some oil on as-received nuts and bolts, but heavy contamination can slow cure and impair strength development. For consistent performance, use clean, dry, grease-free surfaces and test the actual fastener condition. See Permabond's MM115 cleaning guidance.
- Clean the metal surfaces with a suitable solvent-based cleaner such as acetone or isopropanol.
- Prevent the dispensing tip from touching metal.
- For through holes, dispense a bead across the contact length of the threads. For blind holes, apply several drops down the threads to the bottom of the hole.
- Assemble and torque as required; allow the appropriate cure time.
- Replace the bottle lid to avoid contamination.
Handling strength is not full cure or confirmation of readiness for pressure service. MM115 is not recommended for oxygen, oxygen-rich systems or strong oxidizers. It may adversely affect some thermoplastics; verify compatibility before use. Consult the SDS and validate the application before production.
Chemical-Resistance Reference
After 340 hours of immersion at 75°C, the TDS reports strength retention of 100% in water, butyl alcohol, hydrocarbon test fluid and JP5 jet fuel; 99% in toluene, motor oil and ethylene glycol; and 93% in JP4 jet fuel. These results are not a universal fluid-compatibility or pressure rating.

Frequently Asked Questions
Is MM115 removable?
Yes. Permabond describes its medium strength as allowing disassembly with ordinary tools. Actual removal torque depends on the assembly and cure conditions.
What does this listing include?
SKU AA001150001L0101 supplies a case of ten 1-liter bottles.
How long does MM115 take to cure?
Typical handling time is 10 minutes and full-strength time is 24 hours on M10 steel at 23°C. Other substrates, gaps and temperatures change cure speed.
Do nuts and bolts need cleaning first?
MM115 tolerates some oil, but clean, dry, grease-free surfaces provide the most consistent results. Test as-received fasteners, especially if heavily contaminated.
How does it differ from LM113?
MM115 is blue and medium strength, with typical M10 steel breakaway torque of 16 N·m. LM113 is purple and low strength, with typical breakaway torque of 9 N·m.
Can it be used in valve or EV-charger assemblies?
Permabond discusses MM115 in those industries for suitable metal fastener assemblies. Those examples do not establish suitability for every valve, fluid system or charger component; verify the specific joint and service conditions.
Does UV fluorescence prove full cure?
Fluorescence helps detect adhesive presence. Follow the required cure process rather than treating fluorescence alone as proof of full cure.
How should it be stored?
Store at 5–25°C and replace the lid to prevent contamination. Keep the dispensing tip from touching metal during application.
