Loctite 274 Acrylic Anaerobic Threadlocker Blue 50ml

Loctite 274 Acrylic Anaerobic Threadlocker Blue 50ml

• Strength : Medium
• Fixture Time Temperature : 30°C
• Viscosity : 125 mPa.s (cP) Brookfield
• Color : Blue
• Curing Type : Anaerobic
• Application : Threadlocking

 

LOCTITE® 274 is a blue, liquid, 1-part, low viscosity dimethacrylate ester, acrylic threadlocker with medium strength. It is designed for the locking and sealing of threaded fasteners which require normal disassembly with standard hand tools. The product cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration.

• One component – no mixing
• Medium strength
• Disassembly with standard tools
• Positive under UV light

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 black oxide bolts and steel nuts 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 depend on thread type, quality and size.
The following graph shows the 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 black oxide bolts and steel nuts
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 zinc dichromate M10 steel nuts and
bolts using Activator 7471™ or 7649™ 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
Material Safety Data Sheet (MSDS).
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 material is an inactive metal or 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. 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.

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.
