    For quick repairs, these epoxies begin to harden in six minutes or less. Epoxies are the strongest and most chemical-resistant structural adhesives. They bond especially well on metal.
    These adhesives come in two parts that need to be mixed. The container size listed is the combined total of the two parts.
    Thick Liquid—Flow into narrower gaps than gels and pastes, but thick enough to stay put on uneven surfaces.

    Flexible Light-Activated Instant-Bond Adhesives

    Take your time to precisely align parts before bonding, and maintain flexibility afterward. These adhesives won't harden until you expose them to a compatible light source. They also remain elastic so the bond can bend without breaking.
    Thin Liquid—Seep into narrow gaps and joints that thick-liquid adhesives can't reach. Use when bonding close-fitting parts.

    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.

    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).
