    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.

    Mixing required—resin and hardener come in two separate jars or in a jar and syringe and must be combined before applying. Change the mix ratio of these heat-transfer potting compounds to achieve the right hardness for your application. They're formulated to draw heat away from sensitive electronic components, so they 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.
    The size listed is the combined total of the two parts.
