PRODUCT DESCRIPTION
LOCTITE® Product 222 is a single component anaerobic
threadlocking material, which is thixotropic and develops low
strength for easy disassembly. The product cures when
confined in the absence of air between close fitting metal
surfaces.
TYPICAL APPLICATIONS
Prevents loosening through vibration and leakage of threaded
fasteners. Particularly suitable for applications such as
adjustment of set screws, small diameter or long engagement
length fasteners where easy disassembly is required without
shearing the screw.

TYPICAL CURING PERFORMANCE
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. 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 shear strength developed with time on
steel pins and collars at different controlled gaps 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 breakaway strength developed

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 oxidising 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.
Storage
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.
Data Ranges

and/or range (based on the mean value ±2 standard deviations).
Values are based on actual test data and are verified on a
periodic basis.
