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.

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. Product regulations restrict sales to the listed jurisdictions/areas.
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.
