Loctite 2400 Threadlocker Medium Strength

LOCTITE 2400 is a medium strength threadlocker. The product is dimethacrylate-based and blue in colour.

E.g., stainless steel and plated surfaces.

LOCTITE 2400 cures in the absence of air between close-fitting metal surfaces. It prevents loosening and leakage from shock and vibration. This product is a “white label” material. It does not contain any declarable carcinogens, mutagens or toxins.

How to use Loctite 2400:

1. For best results, clean all surfaces with a solvent. Allow it to dry.
2. If using on inactive metal or curing speed is too slow, use an activator spray such as LOCTITE SF 7471 or SF 7649. Allow it to dry.
3. Shake before use. Do not allow the tip to touch the surfaces during application. This will prevent the liquid from clogging in the nozzle.
4. For thru holes. Apply several drops of the product onto the bolt at the nut engagement area.
5. For blind holes. Apply several drops of the product down the internal threads to the bottom of the hole.
6. For sealing applications. Apply a 360° bead of product to the leading threads of the male fitting. Leave the first thread free. For bigger threads: adjust product amount accordingly. Apply product on the female threads also.
7. Assemble and tighten as required.

Storage

Store LOCTITE 2400 in the unopened container in a dry location. Optimal Storage: 8° C to 21° C. Storage below 8° C or greater than 28° C can adversely affect product properties.
