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.

Optically Clear Epoxy Structural Adhesives
For invisible bond lines, these adhesives dry clear. Epoxies are the strongest and most weather- and chemical-resistant structural adhesives. Choose an epoxy 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.
0151 and E-30CL are suitable for fiber-optic applications.

Toughened Epoxy Structural Adhesives
Toughened adhesives are blended with rubber particles for better impact resistance than standard epoxies. They form flexible, resilient bonds. The most weather- and chemical-resistant structural adhesives, epoxies work especially well on metals. 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 with a dispensing gun and mixer nozzle to simultaneously mix and dispense adhesives.
DP420NS, DP460NS, E-40HT, and 9462 are nonsagging, so they won't drip from vertical or overhead surfaces.

Fuel-Resistant Surface Fillers
Also known as sloshing compounds, these two-part epoxies bond to rough and rusty surfaces in fuel tanks to repair leaks and prevent further corrosion. They withstand permanent immersion in fuel, oil, and harsh solvents. Use them with metal, plastic, and fiberglass tanks. Mix the smaller can with the bigger one and pour into your fuel tank. Rotate the tank to coat the interior and dump out any excess. Allow to cure overnight. Size listed is the combined total of the two parts.
1.5-pint container can treat a 10-gallon fuel tank. 3-pint container can treat a 20-gallon fuel tank.
