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.
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.
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.

Urethane Structural Adhesives
Urethane adhesives are the most flexible, so they bond dissimilar materials and damp vibration.
The size listed is the combined total of the two parts. Dispense adhesives in 10.1 fl. oz. cartridges with a standard caulk gun.
5570 is also known as silane modified polymer.

Glue-on-a-Roll

Apply this glue-like tape for a no-mess alternative to liquid adhesives, hot melts, and staples. Also known as adhesive transfer tape, these rolls have a thin film of pressure-sensitive glue on a peel-away liner. They are thinner and more conformable than tape with adhesive on both sides.
9482PC and 9485PC are a good choice for precise applications, even on slippery plastics. They're reinforced with fiber so they keep their shape and don’t ooze out, unlike softer adhesives.
