LOCTITE® EA E-90FL is a gray, opaque, 2-part, toughened, medium viscosity, industrial grade solid epoxy adhesive. After curing at room temperature, it forms a flexible, gray bondline with excellent resistance to shock and impact, a wide range of chemicals and solvents and acts as an excellent electrical insulator. Suited for low-stress, high-impact bonding applications of dissimilar materials.

• Extended working life allows more time to adjust parts during assembly
• Typical applications include bonding plastic, metal, glass, wood, ceramic, rubber, and masonry materials where flexibility is required
• Can also be used for repairing strain gauges, sealing seams on fiberglass components, repairing printed circuit boards, bonding stainless steel inserts, and rubber hose to steel tubing

LOCTITE®
EA E-90FL™ is a toughened, medium
viscosity, industrial grade epoxy adhesive with extended
working life. Once mixed, the two component epoxy cures at
room temperature to form a flexible, gray bondline with
excellent resistance to shock and impact. When fully cured, the
epoxy is resistant to a wide range of chemicals and solvents,
and acts as an excellent electrical insulator. Typical
applications include bonding plastic, metal, glass, wood,
ceramic, rubber, and masonry materials where flexibility is
required. Suited for low-stress, high-impact bonding
applications of dissimilar materials. LOCTITE®
EA E-90FL™
can also be used for repairing strain gauges, sealing seams on
fiberglass components, repairing printed circuit boards,
bonding stainless steel inserts, and rubber hose to steel tubing.
The products extended working life allows more time to adjust
parts during assembly.

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).

Directions For Use:

1. For high strength structural bonds, remove surface
   contaminants such as paint, oxide films, oils, dust, mold
   release agents and all other surface contaminants.
2. Use gloves to minimize skin contact. DO NOT use
   solvents for cleaning hands.
3. Dual Cartridges: To use simply insert the cartridge into
   the application gun and start the plunger into the cylinders
   using light pressure on the trigger. Next, remove the
   cartridge cap and expel a small amount of adhesive to be
   sure both sides are flowing evenly and freely. If automatic
   mixing of resin and hardener is desired, attach the mixing
   nozzle to the end of the cartridge and begin dispensing
   the adhesive. For hand mixing, expel the desired amount of the adhesive and mix thoroughly. Mix for approximately
   15 seconds after uniform color is obtained.
   Bulk Containers: Mix thoroughly by weight or volume in
   the proportions specified in Product Description section.
   Mix vigorously, approximately 15 seconds after uniform
   color is obtained.
4. For maximum bond strength apply adhesive evenly to
   both surfaces to be joined.
5. Application to the substrates should be made within 90
   minutes. Larger quantities and/or higher temperatures
   will reduce this working time.
6. Join the adhesive coated surfaces and allow to cure at
   25 °C for 24 hours for high strength. Heat up to 93 °C, will
   speed curing.
7. Keep parts from moving during cure. Contact pressure is
   neccesary. Maximum shear strength is obtained with a 0.1
   to 0.2 mm bond line.
8. Excessive uncured adhesive can be cleaned up with
   ketone type solvents
