LOCTITE 2422 is a blue, thixotropic, medium strength, dual cure, dimethacrylate ester acrylic threadlocking paste designed for locking and sealing threaded fasteners requiring normal disassembly with standard hand tools. It is particularly suitable for applications on less active substrates such as stainless steel and plated surfaces, where disassembly with hand tools is required for servicing.

• Thixotropic
• Medium strength
• Dual cure
• Designed for locking and sealing threaded fasteners requiring normal disassembly with standard hand tools
• Particularly suited for applications where extreme high temperature resistance is required

LOCTITE®
2422™ is designed for the locking and sealing of
threaded fasteners which require normal disassembly with
standard hand tools. The product cures when confined in the
absence of air between close fitting metal surfaces and
prevents loosening and leakage from shock and vibration.
Particularly suitable for applications on less active substrates
such as stainless steel and plated surfaces, where
disassembly with hand tools is required for servicing.
Particularly suited for applications where extreme high
temperature resistance is required.
 

TYPICAL CURING PERFORMANCE

Cure Speed vs. Substrate

The rate of cure will depend on the substrate used. The graph
below shows the breakloose strength developed with time on
compared to different materials and tested according to ISO
10964, pretorqued to 5 N·m.

Cure Speed vs. Temperature

The rate of cure will depend on the temperature. The graph
below shows the breakloose strength developed with time at
different temperatures on 3/8 x 16 degreased steel nuts & bolts
and tested according to ISO 10964, pretorqued to 5 N·m

Cure Speed vs. Activator

Where cure speed is unacceptably long, or large gaps are
present, applying activator to the surface will improve cure
speed. The graph below shows the breakloose strength
developed with time using Activator 7471™ and Activator
7649™ on zinc dichromate M10 steel nuts and bolts and tested
according to ISO 10964, pretorqued to 5 N·m.

GENERAL INFORMATION

This product is not recommended for use in pure oxygen
and/or oxygen rich systems and should not be selected as
a sealant for chlorine or other strong oxidizing materials.
For safe handling information on this product, consult the
Safety Data Sheet (SDS).
Where aqueous washing systems are used to clean the
surfaces before bonding, it is important to check for
compatibility of the washing solution with the adhesive. In
some cases these aqueous washes can affect the cure and
performance of the adhesive.
This product is not normally recommended for use on plastics
(particularly thermoplastic materials where stress cracking of
the plastic could result). Users are recommended to confirm
compatibility of the product with such substrates.

Directions for use:

For Assembly

1. For best results, clean all surfaces (external and internal)
   with a LOCTITE®
   cleaning solvent and allow to dry.
2. If the material is an inactive metal or the cure speed is too
   slow, spray all threads with Activator 7649™ or Activator
   7471™ and allow to dry.
3. To prevent the product from clogging in the nozzle, do not
   allow the tip to touch metal surfaces during application.
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, leaving the first
   thread free. Force the material into the threads to
   thouroughly fill the voids. For bigger threads and voids,
   adjust product amount accordingly and apply a 360° bead
   of product on the female threads also.
7. Assemble and tighten as required.

For Disassembly

1. Remove with standard hand tools.
2. In rare instances where hand tools do not work because
   of excessive engagement length, apply localized heat to
   nut or bolt to approximately 250 °C. Disassemble while
   hot.

For Cleanup

1. Cured product can be removed with a combination of
   soaking in a Loctite solvent and mechanical abrasion
   such as a wire brush.
