LOCTITE 2701 is a green, low viscosity, methacrylate-based threadlocking adhesive with high strength, especially for chromated surfaces. Steel fixture time of 10 min, brass 4 min and stainless steel 25 min. Tolerates slight contaminations of industrial oils. Suitable for all metal fasteners. Fluoresces under UV light.
- High strength, especially for chromated surfaces
- Low viscosity
- Fluoresces to allow quality control and inspection
- Prevents unwanted movement, loosening, leaks and corrosion
- Resists vibration
- Seals threads - allows through-hole tapping
2701 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. This product is particularly suited for use on inactive
substrates and/or where maximum resistance to hot oil is
TYPICAL CURING PERFORMANCE
Cure Speed vs. Substrate
The rate of cure will depend on the substrate used. The graph
below shows the shear strength developed with time on steel
pins and collars compared to different materials and tested
according to ISO 10123.
Cure Speed vs. Bond Gap
The rate of cure will depend on the bondline gap. The following
graph shows shear strength developed with time on steel pins
and collars at different controlled gaps and tested according to
Cure Speed vs. Temperature
The rate of cure will depend on the temperature. The graph
below shows the shear strength developed with time at
different temperatures on steel pins and collars and tested
according to ISO 10123.
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 shear strength developed
with time on zinc dichromate steel pins and collars using and
tested according to ISO 10123.
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 material is an inactive metal or the cure speed is
too slow, spray all threads with primer and allow to dry.
- 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.
- Apply localized heat to nut or bolt to approximately
250 °C. Disassemble while hot.
- Cured product can be removed with a combination of soaking in
a Loctite solvent and mechanical abrasion such as a wire brush.
