Product Information
Full details
The Bondloc B270-10 Studlock is a permanent, green-colored, general-purpose adhesive designed for permanently securing threaded assemblies up to 1 inch. Its key benefit is providing a strong, reliable lock that seals against leakage and corrosion, eliminating the need for double nutting or welding. A caveat is its permanent nature, making disassembly difficult. This threadlocker offers excellent chemical resistance to fuels, lubricants, and industrial liquids, reduces assembly stress, and can allow for thinner casting designs.

Extended Product Information
FAQs
What does 'permanent' mean for this threadlocker?
Permanent means that once cured, the threadlocker provides a strong, vibration-resistant bond that typically requires heat to disassemble. It is not designed for applications that require frequent removal.
What is the maximum thread size this product can lock?
The Bondloc B270-10 is effective for locking studs and threaded assemblies up to 1 inch (approximately M24) in diameter.
How quickly does it cure?
Without an activator, it achieves fixture in approximately 10 minutes. With an activator, fixture time can be reduced to about 5 minutes. Full cure for maximum strength takes up to 12 hours.
What is the shelf life of Bondloc B270-10?
The product has a minimum shelf life of 12 months from the date of manufacture when stored under recommended conditions (cool, dry, sealed).
Can this threadlocker be used on plastic parts?
This product is designed for metal threaded assemblies. Compatibility with plastics should be tested, as some plastics may be affected by the adhesive or its curing process.
What is the operating temperature range?
The cured adhesive can withstand operating temperatures ranging from -55°C to 180°C.
How do I remove a permanently locked assembly?
To disassemble a permanently locked assembly, local heating to approximately 150-200°C is typically required to soften the adhesive, followed by the use of wrenches.
Troubleshooting
Slow or incomplete cure
Ensure surfaces are clean and dry. Use an activator if operating at low temperatures (<10°C) or if using on inactive metals (e.g., stainless steel, plated surfaces). Check product expiry date.
Adhesive not dispensing
Ensure the nozzle is not blocked. If blocked, carefully clear with a pin or wire. If the product has expired or is significantly aged, it may have cured in the container.
Component loosens after cure
Verify that the product was applied correctly to both mating threads and that sufficient adhesive was used for the thread size and gap. Ensure the parts were assembled within the recommended fixture time and allowed to cure fully.
Difficulty in disassembly
This is expected for a permanent threadlocker. For disassembly, heat the assembly to approximately 150-200°C to soften the adhesive, then use standard tools.
Pros and Cons
Pros
- Provides a permanent and secure lock for threaded assemblies.
- Offers excellent resistance to chemicals, fuels, and lubricants.
- Seals threads effectively, preventing leaks and corrosion.
- Reduces the need for mechanical locking devices or welding.
- Allows for lighter component designs by reducing stress.
- Suitable for a wide range of industrial applications.
Cons
- Permanent nature makes disassembly challenging.
- Requires specific conditions for optimal curing.
- Not suitable for applications requiring frequent disassembly.
- Activator may be required for faster fixture times.
Setup, Compatibility & Care
Setup:
- Ensure all mating surfaces of the threads are clean, dry, and free from oil, grease, and other contaminants.
- For faster fixture times, especially on inactive surfaces or at low temperatures, an activator can be used. Apply activator to one surface and allow it to dry before applying the adhesive.
- Apply the adhesive to the male thread, covering the first few threads.
- Assemble the parts and tighten to the required torque. For permanent applications, ensure full engagement.
- Allow the adhesive to cure fully for 12 hours at room temperature (approx. 20°C) for maximum strength. Partial cure (approx. 2 hours) provides good handling strength.
Compatibility:
- Suitable for all metal threaded assemblies up to 1 inch (M24).
- Compatible with most industrial fluids including fuels, lubricants, and hydraulic oils.
- Works on most plated and unplated metal surfaces.
Care:
- Store in a cool, dry place away from direct sunlight and heat sources.
- Keep the container tightly sealed when not in use.
- Shelf life is a minimum of 12 months from the date of manufacture when stored correctly.
