• 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
• Thixotropic

LOCTITE®
2760™ cures when confined in the absence of air
between close fitting metal surfaces and prevents loosening
and leakage from shock and vibration. LOCTITE®
2760™ 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 where heavy shock and stress levels are
required. The thixotropic nature of LOCTITE®
2760™ reduces
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
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 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.

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, spray all threads with
   Activator 7471™ or 7649™ and allow to dry.
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
   down the internal threads to the bottom of the 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. Where hand tools do not work because of excessive
   engagement length or large diameters (over 1"), apply
   localized heat 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.
