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.
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.

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.
Adhesives that meet ASTM E595, a standard used by NASA, produce almost no volatile emissions that could damage sensitive electronics, even in a vacuum.

Heavy Duty EMI/RFI Shielding Coatings for Electronics
Coat electronics for durability in tough conditions while blocking EMI/RFI signals. Made of epoxy mixed with silver-coated copper, these coatings are stronger than acrylic EMI/RFI coatings. They are rigid enough to withstand the wear of access panels and industrial cabinets. You can also use them in engine compartments because they resist damage from high temperatures and chemicals. Also known as conductive paint, they shield your parts from interference that could cause circuit malfunction and data loss. Mix the two parts of these compounds together and paint them on components. These coatings cannot be sold to Canada due to product labeling requirements.
