Loctite 290 Acrylic Anaerobic Threadlocker Green 50ml

• Strength : Medium to High
• Temperature : -65 - 300 °F
• Viscosity : 25 - 55
• Key Substrates : Metal: Brass, Metal: Steel, Metal: Steel - Stainless Steel
• Color : Green
• Curing Type : Anaerobic

LOCTITE® 290 is a liquid medium/high-strength threadlocker 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 for disassembly prior to application. The product cures when confined in the absence of air between close-fitting metal surfaces and prevents loosening and leakage due to shock and vibration. The product can also fill porosities in welds, castings and powdered metal parts.

• Ideal for locking preassembled fasteners, e.g. instrumentation fasteners, electrical connectors and set screws
• Works on metal only
• Proven to be tolerant of minor contamination due to industrial oils, e.g. motor oils, corrosion prevention oils and cutting fluids
• Requires heat for disassembly

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 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 depends 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. 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 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 the breakaway strength
developed with time on M10 zinc dichromate steel nuts and
bolts using Activator 7471™ and 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 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.
