Frequently Asked Questions

Can I use Loctite 222 on plastics?

This product is not generally recommended for use on plastics, particularly thermoplastic materials, as it may cause stress cracking. We recommend confirming compatibility with your specific substrate before application.

What is the best way to disassemble fasteners treated with Loctite 222?

Under normal conditions, simply use standard hand tools. In rare instances where the engagement length is excessive, apply localized heat to the nut or bolt to approximately 250 °C and disassemble while the component is still hot.

How do I ensure the best curing results?

For maximum performance, clean both internal and external surfaces with a Loctite cleaning solvent and allow them to dry completely before application. If you are working with inactive metals, the use of an activator can help accelerate the cure speed.

What are the optimal storage conditions?

To maintain the integrity of the adhesive, store the unopened container in a dry location between 8 °C and 21 °C. Avoid temperatures below 8 °C or above 28 °C, as this can adversely affect the product's properties.
