Application Bonding
Hysol®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. Hysol®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.
