About Structural Adhesives

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.

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.

Slow-Set Epoxy Structural Adhesives

To allow time to adjust and position parts, these epoxies remain workable for at least 90 minutes. The strongest and most weather- and chemical-resistant structural adhesives, epoxies work especially well on metals.

The size listed is the combined total of the two parts.

Metal-Reinforced Epoxy Structural Adhesives

These machinable epoxies are mixed with metal so they can be used to repair cracks and threaded holes. The strongest and most weather- and chemical-resistant structural adhesives, epoxies work especially well on metals. For putty adhesives, slice off the required amount, then knead it together to form a moldable adhesive.

8267 is reinforced with steel, but won't rust.
