    Even when used underwater, these adhesives maintain their strength. Epoxies are the strongest and most chemical-resistant adhesives. They bond especially well on metal.
    These epoxies come in two parts that need to be mixed. The container size listed is the combined total of the two parts.
    Paste—Thicker than liquid adhesives but still spreadable—good for filling gaps and covering surfaces.
    Putty—Slice off a chunk and mold it into the shape you need.
    Thick Liquid—Flow into narrower gaps than gels and pastes, but thick enough to stay put on uneven surfaces.

    With excellent resistance to corrosive chemicals, these epoxies maintain bonds in tough conditions.
    Epoxies are the strongest and most chemical-resistant structural adhesives. They bond especially well on metal. Choose an adhesive that hardens quickly for fast repairs, or one that hardens slowly to allow more time for positioning.
    These adhesives come in two parts that need to be mixed. The container size listed is the combined total of the two parts.
    Model Number E-120HP—Resist acetone, fuel, and oil. These adhesives also bond dissimilar materials and withstand rapid changes in temperature.
    Model Number 9430—Resist fuel and hydraulic fluid.
    Cartridge—To mix and dispense these adhesives, you'll need a mixer nozzle and dispensing gun.
    Thick Liquid—Flow into narrower gaps than gels and pastes, but thick enough to stay put on uneven surfaces.

    Epoxy Potting Compounds for Harsh Environments

    Image of Product. Front orientation. Potting Compounds. Epoxy Potting Compounds for Harsh Environments.
    Tough enough to be permanently submersed in seawater, these compounds protect sensitive electronics, such as circuit boards, semiconductors, and sensors in harsh environments. They resist moisture, salt, and chemicals, so you can use them in corrosive oil, marine, and mining applications. These compounds can also be used within autoclaves. Because they are epoxies, they are rigid, resist wear, and create excellent electrical insulation. They withstand a wide range of temperatures, and this formulation won’t crack or split as components heat up and cool down.
    They come in a cartridge, so you can apply them precisely. To dispense, they require a mixer nozzle and gun (both sold separately).
