Loctite 243 Threadlocker 10ml

  • Strength : Medium
  • Viscosity : 350 to 3,000 @ 25°C
  • Color : Blue
  • Curing Type : Anaerobic
  • Application : Threadlocking
LOCTITE 243 is a general purpose threadlocker of medium bond strength. This threadlocker secures and seal bolts, nuts and studs to prevent loosening due to vibration. The product works on all metals, including passive substrates such as stainless steel, aluminium and plated surfaces. It is proven to be tolerant of minor contamination due to industrial oils, e.g. motor oils, corrosion prevention oils and cutting fluids.
  • Threadlocking adhesive medium strength, general purpose
  • Prevents loosening on vibrating assemblies, e.g. pumps, gear boxes or presses
  • Works on all metals, including passive substrates (e.g. stainless steel, aluminum, plated surfaces)
  • Proven to tolerate minor contamination by industrial oils, e.g. motor oils, corrosion prevention oils and cutting fluids
  • Permits disassembly with hand tools for servicing
  • Suitable for all metal threaded assemblies
LOCTITE®
243™ is designed for the locking and sealing of
threaded fasteners which require normal disassembly with
standard hand toolsThe product cures when confined in the
absence of air between close fitting metal surfaces and
prevents loosening and leakage from shock and vibrationThe
thixotropic nature of LOCTITE®
243™ reduces the migration of
liquid product after application to the substrateLOCTITE®
243™ provides robust curing performance. It not only works
on active metals (e.g. brass, copper) but also on passive
substrates such as stainless steel and plated surfacesThe
product offers high temperature performance and oil tolerance.
It tolerates minor surface contaminations from various oils,
such as cutting, lubrication, anti-corrosion and protection fluids

TYPICAL CURING PERFORMANCE

Cure Speed vs. Substrate

The rate of cure will depend on the substrate used.The graph
below shows the breakaway strength developed with time on
M10 steel nuts and bolts compared to different materials and
tested according to ISO 10964.
Cure Speed vs. Bond Gap

The rate of cure will depend on the bondline gap.Gaps in
threaded fasteners depends on thread type, quality and size
The following graph shows shear strength developed with time
on steel pins and collars at different controlled gaps and tested
according to ISO 10123
Cure Speed vs. Temperature

The rate of cure will depend on the temperature. The graph
below shows the breakaway strength developed with time at
different temperatures on M10 steel nuts and bolts and tested
according to ISO 10964
Cure Speed vs. Activator

Where cure speed is unacceptably long, or large gaps are
present, applying activator to the surface will improve cure
speedThe graph below shows the breakaway strength
developed with time on M10 zinc dichromate steel nuts and
bolts using Activator 7471™, 7649™, 7088™ and 7091™ and
tested according to ISO 10964
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 cure speed is too slow, use appropriate activator.
    Please see the Cure Speed vs. Activator graph for
    reference. Allow the activator to dry when needed
  3. Shake the product thoroughly before use
  4. To prevent the product from clogging in the nozzle, do
    not allow the tip to touch metal surfaces during
    application
  5. For Thru Holes, apply several drops of the product onto
    the bolt at the nut engagement area
  6. For Blind Holes, apply several drops of the product to
    the lower third of the internal threads in the blind hole, or
    the bottom of the blind hole
  7. 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
  8. 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
  3. Apply localized heat to the assembly 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.
