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.

Surface fillers in one-time-use packets and jars come as two parts. The size listed is the combined total of the two parts.

Surface filler in a pen dispenses as a thin, ready-to-use liquid that fills in pitting and small gaps. It’s often used on circuit boards to fix components or to prototype new systems.

Volume resistivity and surface resistivity measure 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.

An alternative to solder, these flexible, silver-filled adhesives accommodate joint movement. Use them to bond electrical components and repair circuits. The size listed is the combined total of the two parts.

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.

Cartridge potting compound requires a gun and mixer nozzle (each sold separately) to dispense.
