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.

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.

This thermally conductive coating keeps electrical components cool by dissipating heat. Use it to bond transformers, transistors, and other heat-generating components to printed circuit boards and heat sinks.

A safe alternative to mercury in thermometers and thermostats, gallium transfers heat and electricity without toxic vapor that can be inhaled. Also known as Galinstan. Its low melting point means it's liquid at room temperature. When used next to parts that generate concentrated heat, it dissipates the heat quickly, making it good thermal interface material. It also allows electricity to pass throughout it, so it's often used in switches and electronics that must bend and flex.

Gallium clings to both metallic and nonmetallic surfaces such as glass and quartz. However, it eats away at most metal when used at high temperatures and dissolves aluminum even at ambient temperatures.

When choosing gallium, keep in mind its composition. The higher the gallium and indium content, the better it is at transferring heat. Gallium with tin reduces the melting point, but also decreases how well it transfers heat.

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.

A high silver content gives this grease excellent conductivity for applications where electricity and heat transfer are required. It is suitable for ESD (electrostatic discharge) and EMI (electromagnetic interference) shielding applications. Product regulations restrict sales to the listed jurisdictions/areas.

NLGI viscosity grade is a rating of a grease's consistency. NLGI 2 is about the consistency of peanut butter.

Electrical resistivity is a measure of 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.

Grease lubricates most efficiently within the listed temperature range. Melting temperature is the point at which grease will fail and run out of equipment, leaving it to run dry.

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.

Carbon acrylic pens should be used where only a small amount of conductivity is needed, such as circuit boards in keyboards. Their high surface resistivity only allows a small current to pass.

Nickel acrylic pens are best for general purpose repairs, such as bridges and traces in printed circuit boards. They have a medium surface resistivity, so they're a good balance between carbon acrylic and silver epoxy pens.

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.
