General Description
SpiderAdhesive EST-FL40 is a two part 1:1, toughened, medium viscosity, industrial grade epoxy adhesive with a medium working life.
Once mixed, the two component epoxy cures at room temperature to form a flexible, gray bonding line 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.

Chemical Type (Resin) | Epoxy |
Chemical Type (Hardener) | Polyamide |
Appearance (Resin) | Off-white to beige liquid |
Appearance (Hardener) | Dark gray liquid |
Appearance (Mixture) | Gray, opaque liquid |
Components | Two component 1:1 (requires mixing) |
Viscosity | Medium |
Mix Ratio, (by volume) | Resin : Hardener = 1 : 1 |
Mix Ratio, by weight | Resin : Hardener 100 : 85 |
Cure | Room temperature cure after mixing |
Application | Bonding |
Typical applications
1/ 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.
2/ Repairing strain gauges, sealing seams on fiberglass components, repairing printed circuit boards,
3/Bonding stainless steel inserts, and rubber hose to steel tubing.
