Permabond AA00115P050B0101, MM115 Pure, Anaerobic Threadlocker, 50ml Bottle, Case of 10
Permabond AA00115P050B0101, MM115 Pure, Anaerobic Threadlocker, 50ml Bottle, Case of 10
Permabond MM115 PURE is a medium-strength anaerobic threadlocker and sealant designed for use in contact with potable water. It locks metal bolts, nuts and screws that may require disassembly for service and maintenance, with medium strength that allows removal using ordinary tools. SKU AA00115P050B0101 supplies ten 50 mL bottles per case.
Unlike standard blue MM115, MM115 PURE is colorless to light amber and has no UV fluorescence. Select the exact grade specified for your assembly rather than treating the two as interchangeable.
Best Uses / Applications
- Metal threaded assemblies where a potable-water-contact formulation is required, subject to application-specific qualification.
- Serviceable metal bolts, nuts and screws in industrial equipment.
- Maintenance applications requiring medium strength and ordinary-tool disassembly.
- Steel, cadmium, zinc and other plated metal fasteners, with cure conditions validated for the actual surface.
Key Features
- Medium strength with controlled off-torque.
- Designed for potable-water contact.
- Non-drip, thixotropic formulation.
- Lubricates threads for easier assembly and provides corrosion protection.
- Full cure at room temperature; 100% solids formulation.
- Colorless to light amber, without UV fluorescence.

Values are typical manufacturer data, not guaranteed assembly specifications. Copper alloys accelerate cure; passivated or oxidized surfaces such as stainless steel can slow it. Lower temperatures and larger gaps extend cure time. Permabond identifies A905, ASC10 or heat as options to reduce cure time; validate any process change for the intended application.

Surface Preparation & Application
The PURE TDS notes that anaerobic adhesives tolerate a slight degree of surface contamination, but best results are obtained on clean, dry, grease-free surfaces. Use a suitable solvent-based cleaner such as acetone or isopropanol and validate the actual assembly.
- Keep the dispensing tip from touching metal surfaces.
- 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 the parts as required.
- Replace the bottle lid to avoid contamination and allow the required cure time.
Handling strength is not full cure or confirmation of readiness for pressure service. MM115 PURE is not recommended for oxygen, oxygen-rich systems or strong oxidizers. It may adversely affect some thermoplastics; verify compatibility before use. Consult the SDS.
Water-Contact Selection
The manufacturer TDS describes MM115 PURE as designed for potable-water contact and reports NSF/ANSI 61 certification in that document. This dated technical reference does not establish current certification scope or approval of a finished assembly. Obtain current manufacturer certification details and applicable use conditions before specifying it for a regulated drinking-water application.
Chemical-Resistance Reference
After 340 hours of immersion at 75°C, the PURE 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 92% in JP4 jet fuel. These test results are not universal fluid-compatibility or pressure ratings.

Frequently Asked Questions
What does this listing include?
SKU AA00115P050B0101 supplies a case of ten 50 mL bottles of MM115 PURE.
How is PURE different from standard MM115?
PURE is colorless to light amber, has no UV fluorescence and is designed for potable-water contact. Standard MM115 is blue and UV fluorescent. Confirm the exact grade required.
Is MM115 PURE removable?
Yes. Its medium strength allows disassembly using ordinary tools. Actual removal torque depends on the assembly and curing conditions.
How long does it take to cure?
Typical handling time is 10 minutes and full-strength time is 24 hours on M10 steel at 23°C. Substrate, gap and temperature affect cure speed.
Should I clean the fasteners first?
Yes. The manufacturer recommends clean, dry, grease-free surfaces for best results, even though anaerobic adhesives can tolerate slight contamination.
Can it be specified for drinking-water equipment?
The TDS identifies potable-water-contact use and reports NSF/ANSI 61 certification. Confirm current certification scope, use conditions and finished-assembly requirements with the manufacturer before specification.
Can UV light be used to detect MM115 PURE?
The TDS lists no UV fluorescence for PURE. Do not carry over the UV inspection feature of standard blue MM115.
How should it be stored?
Store at 5–25°C, keep the lid replaced and avoid contaminating the dispensing tip through contact with metal.
