FAQs

Q1: How do I remove the Red Threadlocker?
A1: Red threadlocker forms a permanent bond. To remove, apply direct heat (above 260°C/500°F) and use proper tools for extraction.

Q2: Can I use these on plastic or non-metal fasteners?
A2: No. Perma-Lock threadlockers are formulated for metal-to-metal applications only.

Q3: How long does it take to cure?
A3: Full cure typically takes 24 hours. Handling strength may be achieved within 10–20 minutes depending on the material and conditions.

Q4: Are both versions suitable for automotive use?
A4: Yes. The Blue version is ideal for general automotive maintenance, while Red is suited for high-vibration, high-load areas like engine components.
