LOCTITE®290™
December-2013
PRODUCT DESCRIPTION
LOCTITE®290™ provides the following product
characteristics:
Technology Acrylic
Chemical Type Dimethacrylate ester
Appearance (uncured) Green liquidLMS
Fluorescence Positive under UV lightLMS
Components One component -
requires no mixing
Viscosity Low
Cure Anaerobic
Secondary Cure Activator
Application Threadlocking
Strength Medium to High
LOCTITE®290™ is designed for the locking and sealing of
threaded fasteners. Because of its low viscosity and capillary
action, the product wicks between engaged threads and
eliminates the need to disassemble prior to application. The
product cures when confined in the absence of air between
close fitting metal surfaces and prevents loosening and
leakage from shock and vibration. The product can also fill
porosity in welds, castings and powdered metal parts.
Mil-S-46163A
LOCTITE®290™ is tested to the lot requirements of Military
Specification Mil-S-46163A. Note: This is a regional approval.
Please contact your local Technical Service Center for more
information and clarification.
ASTM D5363
Each lot of adhesive produced in North America is tested to
the general requirements defined in paragraphs 5.1.1 and
5.1.2 and to the Detail Requirements defined in section 5.2.
NSF International
Registered to NSF Category P1 for use as a sealant where
there is no possibilty of food contact in and around food
processing areas. Note: This is a regional approval. Please
contact your local Technical Service Center for more
information and clarification.
NSF International
Certified to ANSI/NSF Standard 61 for use in commercial and
residential potable water systems not exceeding 82° C. Note:

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

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 Pre-assembled Threaded Parts with Thru Holes
1. Prior to assembly, clean all threads (bolt and hole) with a
LOCTITE® cleaning solvent and allow to dry.
2. For Thru Holes, apply several drops of product at screw
and body juncture.
3. Avoid touching the bottle tip to the metal surface.
For Assembly
1. For Blind Holes, apply several drops of the product
down the internal threads to the bottom of the hole
For Porosity Sealing
1. Clean area and apply localized heat to the area to
approximately 121°C.
2. Allow to cool to approximately 85°C and apply the
product.
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.
