LOCTITE® 263 is a red, dual cure, acrylic dimethacrylate ester fluorescent threadlocker designed for the permanent locking and sealing of threaded fasteners. It cures between close fitting metal surfaces and prevents loosening and leakage from shock and vibration. It works on active metals (e.g. brass, copper) and passive substrates such as stainless steel and plated surfaces.

• Designed for the permanent locking and sealing of threaded fasteners
• Prevents loosening and leakage from shock and vibration
• Particularly suited for heavy duty applications such as studs into motor housings where high strength is required
• Provides robust curing performance
• Offers high temperature performance and oil tolerance

LOCTITE®
263™ is designed for the permanent locking and
sealing of threaded fasteners. The product cures when confined
in the absence of air between close fitting metal surfaces and
prevents loosening and leakage from shock and vibration
LOCTITE®
263™ is particularly suited for heavy duty
applications such as studs into motor housings, nuts onto studs
in pump housings and other fasteners where high strength is
required LOCTITE®
263™ 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
surfaces. The 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
speed. The 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. 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 to the lower
   third of the internal threads in the blind hole, or the bottom of the
   blind hole
6. For Sealing Applications, apply a 360° bead of product to the
   leading threads of the male fitting, leaving the first thread
   free. 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. 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
