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.
