Epoxy Structural Adhesives
Epoxies are the strongest and most weather- and chemical-resistant structural adhesives. They work especially well on metals.
Two-part epoxies 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.
DP110, 14310, 14260, and 305-1/2 bond dissimilar materials.
DP125, 14255, and 14251 form flexible bonds.

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.
These have two parts that must be mixed. 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.

Epoxy Potting Compounds
Encase electronic assemblies in a layer of epoxy for protection from dust, chemicals, moisture, mechanical shock, and vibration. The strongest of the potting compounds, epoxies are rigid and wear resistant. They have excellent chemical and moisture resistance, withstand a wide range of temperatures, and provide excellent electrical insulation. All require a mixer nozzle and gun to dispense.
3M DP460EG and DP4XLEG also require a plunger to dispense.
