Quick-Set Epoxy Structural Adhesives
For quick repairs, these epoxies begin to harden in 6 minutes or less. Epoxies are the strongest and most weather- and chemical-resistant structural adhesives.
These have two parts that must be mixed. The size listed is the combined total of the two parts. Use cartridges with a dispensing gun and mixer nozzle to simultaneously mix and dispense adhesives.
HY4090 is a blend of epoxy and instant-bond adhesive for a balance of strength, cure speed, and temperature resistance.

Epoxy Structural Adhesives for Harsh Environments
With excellent resistance to corrosive chemicals and salt water, these epoxies work in tough conditions. Epoxies are the strongest structural adhesives. Choose an adhesive that hardens quickly for fast repairs, or one that hardens slowly to allow more time for positioning.
These have two parts that must be mixed. The size listed is the combined total of the two parts. Use cartridges with a dispensing gun and mixer nozzle to simultaneously mix and dispense adhesives.

Epoxy Structural Adhesives for Hard-to-Bond Materials
Fasten hard-to-bond plastics, such as polypropylene and polyethylene, with these adhesives. They bond dissimilar materials. Epoxies are the strongest and most weather- and chemical-resistant structural adhesives. Choose an adhesive that hardens quickly for fast repairs, or one that hardens slowly to allow more time for positioning.
These have two parts that must be mixed. The size listed is the combined total of the two parts. Use cartridges with a dispensing gun and mixer nozzle to simultaneously mix and dispense adhesives.

Flexible Light-Activated Instant-Bond Adhesives
These adhesives stay pliable for flexible bonds that resist cracking. For easy positioning, they begin to harden only when exposed to light.
1700A257 and 2454N1 fluoresce under UV light for easy inspection.

Epoxy Potting Compounds for Harsh Environments
Tough enough to be permanently submersed in seawater, these compounds protect sensitive electronics, such as circuit boards, semiconductors, and sensors in harsh environments. They resist moisture, salt, and chemicals, so you can use them in corrosive oil, marine, and mining applications. These compounds can also be used within autoclaves. Because they are epoxies, they are rigid, resist wear, and create excellent electrical insulation. They withstand a wide range of temperatures, and this formulation won’t crack or split as components heat up and cool down.
They come in a cartridge, so you can apply them precisely. To dispense, they require a mixer nozzle and gun (both sold separately).
