Loctite 272 Acrylic Anaerobic Threadlocker Red 50ml



Loctite 272 Acrylic Anaerobic Threadlocker Red 50ml

  • Strength : High
  • Temperature : -65 - 450 °F
  • Viscosity : 4000 - 15000 mPa.s (cP) Brookfield
  • Key Substrates : Metal: Steel
  • Color : Red
  • Curing Type : Anaerobic
  • Application : Threadlocking

LOCTITE® 272 is a red, medium viscosity, methacrylate-based threadlocking adhesive with high strength. With a fixture time on steel of 10 min, brass 5 min and stainless steel 15 min, it is ideal for applications where any migration of the adhesive must be prevented. Can tolerate slight contaminations of industrial oils. Suitable for all metal fasteners. It has a breakaway torque on M10 bolts of 23 Nm.

  • Medium viscosity
  • Breakaway torque on M10 bolts of 23 Nm
  • High temperature resistant
  • Resists vibration
  • High strength
  • Seals threads - allows through-hole tapping
LOCTITE® Product 272 is a single component, anaerobic
threadlocking material which develops high strength and high
temperature resistance. This product cures when confined in
the absence of air between close fitting metal surfaces.

Prevents loosening and leakage of threaded fasteners.
Typical applications include high temperature locking and
sealing of studs, nuts, screws, bolts and fittings. It is best
suited for applications where the temperatures range up to

Cure Speed vs. Substrate

The rate of cure will depend on 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. Temperature

The rate of cure will depend on the temperature. The
following graph 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 breakaway strength
developed with time using ACTIVATOR N and T on Zinc
Dichromate nuts & bolts and tested according to ISO 10964.

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 best performance surfaces should be clean and free of
grease. Product should be applied to the bolt in sufficient
quantity to fill all engaged threads. This product performs best
in thin bond gaps, (0.05mm). Very large thread sizes may
create large gaps which will affect cure speed and strength.
This product is designed to give controlled friction,
(torque/tension ratio), during assembly. In critical tightening
applications this ratio should be confirmed.

Product shall be ideally stored in a cool, dry location in
unopened containers at a temperature between 8°C to 28°C
(46°F to 82°F) unless otherwise labelled. Optimal storage is
at the lower half of this temperature range. To prevent
contamination of unused product, do not return any material to
its original container. For further specific shelf life information
contact your local Technical Service Centre.
