FAQs
What does 'High Strength' mean for this threadlocker?
'High Strength' indicates that once cured, the threadlocker provides a permanent bond that resists vibration and shock. Disassembly typically requires heat.
Can this threadlocker be used on plastic parts?
This particular product (Green, High Strength) is designed for metal applications. Using it on plastics may cause stress cracking or damage. Always check product compatibility for specific materials.
How long does it take for the threadlocker to fully cure?
Full cure typically occurs within 24 hours at room temperature (20°C). Lower temperatures will result in a longer cure time, while higher temperatures may speed it up slightly.
What is WRAS approval and why is it important?
WRAS approval signifies that the product meets strict standards for use in public water supplies in the UK, ensuring it does not affect water quality. This makes it safe for use in potable water systems.
How do I remove a joint secured with Loctite Green?
To disassemble a joint secured with Loctite High Strength Threadlocker, heat is typically required. Apply localized heat to the assembly to approximately 300°C. Once heated, the fastener can usually be disassembled with hand tools.
Will this threadlocker work on stainless steel?
Yes, this threadlocker works on all metals, including passive substrates like stainless steel, aluminum, and plated surfaces. For optimal cure speed on these materials, an activator might be recommended.
What is the maximum thread size recommended for this product?
This product is generally recommended for thread sizes up to M20. For larger threads, consult the product's technical data sheet for specific application guidelines.
Troubleshooting
Product not curing or curing slowly.
Ensure surfaces are clean and dry. For passive metals, an activator may be needed. Check ambient temperature; lower temperatures slow curing. Ensure adequate thread engagement.
Difficulty in disassembling a locked joint.
Apply localized heat to the assembly (around 300°C) to break down the adhesive. Use appropriate tools for disassembly after heating.
Product appears to be dried out in the tube.
This indicates the cap may not have been sealed properly or the product has been stored for an extended period. Discard and use a fresh tube.
Weak bond strength.
Ensure surfaces were properly cleaned and degreased. Verify that the correct type of threadlocker was used for the application and that sufficient time was allowed for full cure. For passive metals, ensure an activator was used if recommended.
Pros and Cons
Pros
- Provides permanent locking to prevent loosening from vibration.
- Effective on a wide range of metals, including stainless steel and aluminum.
- WRAS approval makes it safe for potable water applications.
- Can be disassembled with heat for maintenance.
- Enhanced performance on specialized coatings like zinc-flake steel.
Cons
- Requires heat (300°C) for disassembly, making it permanent without this step.
- Small 5g tube may not be sufficient for very large or numerous applications.
- Not designed for quick assembly or frequent disassembly without heat.
- Cure time may vary depending on substrate and environmental conditions.
Setup, Compatibility & Care
Setup:
- Ensure all surfaces to be treated are clean, dry, and free from oil, grease, and other contaminants. Degreasing is recommended.
- For passive metals (like stainless steel, aluminum, or plated surfaces), an activator may be required for optimal cure speed. Consult the product technical data sheet for specific recommendations.
- Apply the threadlocker to the male threads, ensuring complete coverage.
- Assemble the parts immediately and tighten to the required torque.
- Allow the product to cure fully. Full cure typically takes 24 hours at 20°C. Cooler temperatures will extend cure time.
Compatibility:
- Suitable for all metal threaded fasteners, including stainless steel, aluminum, and plated surfaces.
- Recommended for thread sizes up to M20.
- WRAS approved for use in potable water systems.
Care:
- Store in a cool, dry place away from direct sunlight and heat sources.
- Keep the cap tightly closed when not in use to prevent premature curing.
- Handle with appropriate personal protective equipment (gloves, eye protection).
