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.

Insulating Adhesives for Electronics
Secure hardware on circuit boards while insulating current.
Cyanoacrylate adhesives dry more quickly than epoxy adhesives. They’re also known as super glue. Use them to secure coils of wire. To create adhesion, they require an accelerator (included with some adhesives).
Epoxy adhesives are two-part adhesives that need to be mixed. The size listed is the combined total of the two parts. Loctite® 2151 resist salts, mild acids, and oils. They can also handle sudden impacts and shocks. Epoxy adhesives that reach full strength in 120 hrs. are flexible, making them ideal for bonding dissimilar materials that may shift or expand differently under heat.
Thermoplastic adhesives create an instant bond, so they’re the best choice for automated assembly lines. The bond is weaker than that of epoxy and cyanoacrylate adhesives, but it’s sufficient for attaching heat sinks. Since they remain tacky, you can detach and reposition parts.
Adhesives that meet ASTM E595, a standard used by NASA, release almost no volatile emissions that could damage sensitive electronics, even in a vacuum.
