    Epoxy adhesives are two-part adhesives that need to be mixed together. The size listed is the combined total of the two parts.
    ASTM E595—Adhesives that meet ASTM E595, a standard used by NASA, produce almost no volatile emissions that could damage sensitive electronics, even in a vacuum.

    Plastic adhesives are one-part adhesives that don’t need to be mixed. Dry to the touch and faster and easier to apply than two-part adhesives, they’re best for use on automated assembly lines. Often used to join solar cells in solar panels, these adhesives make instant electrical connections without flux at lower temperatures than soldering. Since they attach to solar cells with heat and slight pressure, they limit stress cracks that can form when soldering. These adhesives can also be used as a bridge between multiple solar panels.

    Dispense ready-to-use conductive liquid to fill pits and small gaps on circuit board components. These pens are also used to sketch and repair conductive pathways.
    Carbon Filled—Carbon acrylic plastic pens should be used where only a small amount of conductivity is needed, such as circuit boards in keyboards. Their high surface resistivity only allows a small current to pass.
    Nickel Filled—Nickel acrylic plastic pens are best for general purpose repairs, such as bridges and traces in printed circuit boards. They have a medium surface resistivity, so they're a good balance between carbon acrylic and silver epoxy pens.
    Silver Filled—Silver epoxy pens are the most versatile—use them for any type of repair as well as for repairs that require excellent conductivity, such as connecting through holes on circuit boards without adding jumpers, wiring, or solder. Since they have the lowest surface resistivity, they allow the most current to pass.
    Cannot Be Sold To—Product labeling requirements restrict sales to the listed areas.

    A high silver content allows these surface fillers to conduct electricity and heat. Use them to fill gaps and rebuild missing material on electrical connections or to assemble new components. They come as two parts. The size listed is the combined total of the two parts.
    Thermal Conductivity—Thermal conductivity measures a material’s ability to transfer heat. The higher the rating, the more heat it transfers.
    Electrical Volume Resistivity—Electrical volume resistivity measures how well a material opposes the flow of electricity. The lower the rating, the more electricity it conducts.

    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.
