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.
50132 works especially well on plastics and composites.

Epoxy Structural Adhesives
Epoxies are the strongest and most weather- and chemical-resistant structural adhesives. They work especially well on metals. For putty adhesives, slice off the required amount, then knead it together to form a moldable adhesive.

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.

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.

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.
467MP and 468MP resist solvents and UV rays.
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.
