    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.
    Cartridge—To mix and dispense these adhesives, you'll need a mixer nozzle and dispensing gun.
    Gel—Stick in place and keep their exact shape with no flowing or sagging.
    Thick Liquid—Flow into narrower gaps than gels and pastes, but thick enough to stay put on uneven surfaces.

    Cartridge

    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.
    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.

    Heat-Transfer Epoxy Potting Compounds

    Formulated to draw heat away from sensitive electronic components, these potting compounds have higher thermal conductivity than standard potting compounds. Use them to encase electronic assemblies for protection from dust, chemicals, moisture, mechanical shock, and vibration. Rigid and wear resistant, epoxies are the strongest of the potting compounds. They have excellent chemical and moisture resistance, withstand a wide range of temperatures, and provide excellent electrical insulation.

    Handle potted items within minutes—these potting compounds dry quickly when exposed to UV light. For added strength and durability, cure them with heat. Since they’re epoxy, they won’t break down from chemicals or moisture. They’re also excellent electrical insulators and withstand a wide range of temperatures. Use them to shield components from dust, moisture, chemicals, mechanical shock, and vibration. You need a mixer nozzle (not included) and a gun and plunger (both sold separately) to dispense. The nozzle lets you apply these compounds precisely.
    For maximum effectiveness, these compounds need to be heat cured after they’re cured with UV light. Overall dry time includes heat curing at 149° F.

    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.
