FAQs
What is the primary purpose of Liqui Moly Screw Retainer High Strength?
Its primary purpose is to permanently secure threaded connections against vibration and shock, and to seal threads, preventing leaks.
Can this product be used on stainless steel or plated fasteners?
Yes, it is suitable for use on most metal substrates, including stainless steel and plated fasteners.
How long does it take to cure?
Curing time varies with temperature and the gap between threads. Typically, it achieves handling strength within minutes and full cure within 24 hours, but refer to the product's specific instructions for precise details.
Is this product suitable for applications that require frequent disassembly?
No, due to its high-strength formula, this product is intended for permanent assemblies and can make disassembly difficult.
Can I use this on plastic parts?
This product is primarily designed for metal-to-metal applications. Its suitability for plastic depends on the plastic type and the operating temperatures, which may cause degradation.
What is the operating temperature range?
It has a wide operating temperature range, from -60 °C to +150 °C.
How should I store the product?
Store in a cool, dry place, tightly sealed, away from direct sunlight and extreme temperatures to prevent premature curing.
Troubleshooting
Retainer not curing properly
Ensure correct application temperature range is met. Verify that the surfaces are adequately cleaned and that the parts are brought into close contact. Insufficient activator or contamination can also hinder curing.
Difficulty in disassembly
This is expected with a high-strength retainer. Use appropriate tools (e.g., a soldering iron to heat the fastener area to approx. 250°C) and sufficient leverage. Gradual heating can help break the bond.
Leakage persists after application
Confirm that the retainer was applied to the entire thread surface and that sufficient material was used. Ensure the fastener was tightened correctly to allow the retainer to spread and seal.
Pros and Cons
Pros
- Prevents critical components from loosening due to vibration.
- Seals threads effectively, reducing the risk of leaks.
- Maintains performance across a broad temperature range.
- Can be applied to slightly oiled surfaces, simplifying preparation.
- Provides excellent chemical resistance for durability.
Cons
- High-strength formula can make disassembly difficult.
- Requires specific tools or methods for removal.
- Not suitable for applications requiring frequent disassembly.
Setup, Compatibility & Care
Setup:
- Ensure surfaces are clean and free from excessive grease, dirt, or rust. While it can be used on slightly oiled surfaces, optimal performance is achieved on clean threads.
- Apply the retainer directly to the threads of the screw, bolt, or stud before assembly.
- Assemble the parts as usual and tighten to the recommended torque.
- Allow adequate curing time (refer to product instructions for specific times based on temperature and material) before subjecting the assembly to full load or vibration.
Compatibility:
- Compatible with all standard nut and screw sizes and grades.
- Suitable for use on various metals and alloys commonly found in automotive applications.
Care:
- Store in a cool, dry place away from direct sunlight and extreme temperatures.
- Keep the container tightly sealed when not in use to prevent premature curing.
