Loctite 2760 Threadlocker
Loctite 2760 Primerless High Strength Threadlocker 50ml
- Strength : High
- Viscosity : Medium, thixotropic
- Color : Red
- Curing Type : Anaerobic
- Application : Threadlocking
LOCTITE 2760 is a red, homogenous, high strength, thixotropic, dimethacrylate ester acrylic liquid threadlocker which is particularly fast curing thereby reducing or eliminating the need for activators. Particularly suited for heavy duty applications such as bolts used in transmissions, construction equipment or railroad assemblies. Its thixotropic nature reduces migration of the liquid product.
- High strength
- Particularly fast curing
- No activators required
2760™ cures when confined in the absence of air
between close fitting metal surfaces and prevents loosening
and leakage from shock and vibration. LOCTITE®
particularly fast curing thereby reducing or eliminating the need
for activators. Particularly suited for heavy duty applications
such as bolts used in transmissions, construction equipment or
railroad assemblies where heavy shock and stress levels are
required. The thixotropic nature of LOCTITE®
the migration of liquid product after application to the substrate.
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
3/8 x 16 steel nuts & bolts compared to different materials and
tested according to ISO 10964. All samples pre-torqued to 5
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 steel nuts & bolts and tested
according to ISO 10964. All samples pre-torqued 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 7649™ on 3/8
x 16 zinc dichromate steel nuts and bolts and tested according
to ISO 10964. All samples pre-torqued to 5 N·m.
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 best results, clean all surfaces (external and
internal) with a LOCTITE®
cleaning solvent and allow to
- If the cure speed is too slow, spray all threads with
Activator 7471™ or 7649™ and allow to dry.
- 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
- 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
down the internal threads to the bottom of the 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.
- Remove with standard hand tools.
- Where hand tools do not work because of excessive
engagement length or large diameters (over 1"), apply
localized heat to approximately 250 °C. Disassemble
- Cured product can be removed with a combination of
soaking in a Loctite solvent and mechanical abrasion
such as a wire brush.
