Conductive Adhesives for Electronics
An alternative to solder, these flexible, silver-filled adhesives accommodate joint movement. Use them to bond electrical components and repair circuits.
Epoxy adhesives are two-part adhesives that need to be mixed together. The size listed is the combined total of the two parts.
Thermoplastic 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.
Adhesives that meet ASTM E595, a standard used by NASA, produce almost no volatile emissions that could damage sensitive electronics, even in a vacuum.

Ceramic Adhesives
Often used for bonding and repair on exhaust systems, diesel engines, and gas turbines, these adhesives withstand high temperatures and provide excellent electrical insulation. Pastes will not drip or sag while hardening on a vertical surface, while thick liquids flow into small spaces and are easy to spread.

High-Temperature Glue
This high-temperature glue sticks quickly, but can be repositioned for up to 2 hours before it begins to harden. Glue can be applied and allowed to dry, then reactivated with water when ready for bonding. It cannot be sold to Canada due to import regulations.

Conductive Surface Fillers for Electronics
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.
Volume resistivity measures how well a material opposes the flow of electricity. The lower the rating, the more electricity it conducts.
Thermal conductivity measures a material’s ability to transfer heat. The higher the rating, the more heat it transfers.

Conductive Surface Filler Pens for Electronics
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.
Product labeling requirements restrict sales to the listed areas.
Carbon acrylic 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 acrylic 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 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.
