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.

Mixing required—resin and hardener come in two separate jars or in a jar and syringe and must be combined before applying. Change the mix ratio of these heat-transfer potting compounds to achieve the right hardness for your application. They're formulated to draw heat away from sensitive electronic components, so they 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.

The size listed is the combined total of the two parts.

Tested to meet ASTM E595, a standard used by NASA, these potting compounds release almost no volatile emissions that could damage sensitive electronics, even in a vacuum. Use them to draw heat away from your components—they conduct heat better than standard potting compounds. Made of epoxy, they’re the strongest of the potting compounds, so they’re rigid and wear resistant. They’ll also resist breaking down from chemicals and moisture. These compounds are excellent at insulating current, and they’ll shield against dust, vibration, and shock.

To apply, mix the two parts together and pour them over components inside a container, such as a potting box.

Protect circuit boards and other electronics where high heat is a concern but you don’t need to transfer that heat elsewhere. These compounds are a good middle ground between standard epoxy compounds and heat-transfer compounds. They work at temperatures twice as high as standard epoxy compounds. However, they don't conduct heat as well as heat-transfer compounds so they're not the best choice for circuit boards that run for long periods of time. Harden these compounds at room temperature—they don’t require an oven to harden like heat-transfer compounds do.

Since they’re an epoxy compound, they won’t break down from chemicals or moisture. They’re also excellent electrical insulators and withstand a wide range of temperatures. Use them to shield components from dust, moisture, chemicals, mechanical shock, and vibration.

Jar and syringe compounds are the consistency of honey once they’re mixed, so they’ll seep into the crevices of a circuit board and encapsulate intricate components. Use the syringe for precise application.

Bottle compounds are easier to apply in higher volumes than jar and syringe compounds. Mix them together and pour them over components inside containers, such as a potting box. If air bubbles occur after mixing, you can put the mixture in a vacuum chamber to remove them. They cannot be sold to Canada due to product labeling requirements.

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.

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.

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.
