Loctite 243 Threadlocker 10ml
Description
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
Registered to NSF Category P1 for use as a sealant where
there is no possibility of food contact in and around food
processing areas. Note: This is a regional approval. Please
contact your local Technical Service Center for more
information and clarification.
Certified to ANSI/NSF Standard 61 for use in commercial and
residential potable water systems not exceeding 82° C. Note:
This is a regional approval. Please contact your local Technical
Service Center for more information and clarification.
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.
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
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
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
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.
LMS dated June-29, 2009. Test reports for each batch are available
for the indicated properties. LMS test reports include selected QC test
parameters considered appropriate to specifications for customer use.
Additionally, comprehensive controls are in place to assure product
quality and consistency. Special customer specification requirements
may be coordinated through Henkel Quality.
Store product in the unopened container in a dry location. Storage
information may be indicated on the product container labeling.
Optimal Storage: 8 °C to 21 °C. Storage below 8 °C or greater
than 28 °C can adversely affect product properties. Material
removed from containers may be contaminated during use. Do not
return product to the original container. Henkel Corporation cannot
assume responsibility for product which has been contaminated or
stored under conditions other than those previously indicated. If
additional information is required, please contact your local Technical

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

This product is not normally recommended for use on plastics
(particularly thermoplastic materials where stress cracking of the

of the product with such substrates.
Directions for use:
For Assembly
- For best results, clean all surfaces (external and internal)
with a LOCTITE®
cleaning solvent and allow to dry - 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 - Shake the product thoroughly before use
- To prevent the product from clogging in the nozzle, do
not allow the tip to touch metal surfaces during
application - For Thru Holes, apply several drops of the product onto
the bolt at the nut engagement area - 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 - 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 - Assemble and tighten as required
For Disassembly
- Remove with standard hand tools
- 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 - Apply localized heat to the assembly to approximately
250 °C. Disassemble while hot
For Cleanup
- Cured product can be removed with a combination of
soaking in a Loctite solvent and mechanical abrasion
such as a wire brush.
