Combine the flexibility of silicone with the durability of standard epoxy—these compounds are great for protecting sensitive electronics that need to flex or expand and contract. Because they’re an epoxy, they still have excellent moisture, chemical, and abrasion resistance. They withstand a wide range of temperatures, and this formulation won’t crack or split as components heat up and cool down. These compounds are excellent electrical insulators, and they’ll shield your components from moisture and dust. You can also use them as an adhesive since they’re also tacky.

They come in a cartridge, so you can apply them precisely. To dispense, they require a mixer nozzle and gun (both sold separately).

Tough enough to be permanently submersed in seawater, these compounds protect sensitive electronics, such as circuit boards, semiconductors, and sensors in harsh environments. They resist moisture, salt, and chemicals, so you can use them in corrosive oil, marine, and mining applications. These compounds can also be used within autoclaves. Because they are epoxies, they are rigid, resist wear, and create excellent electrical insulation. They withstand a wide range of temperatures, and this formulation won’t crack or split as components heat up and cool down.

They come in a cartridge, so you can apply them precisely. To dispense, they require a mixer nozzle and gun (both sold separately).

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.

Clear enough to read through, these UV-resistant potting compounds allow optimal light transmission for use with LEDs, solar cells, and fiber optics. Use them to encase electronic assemblies for protection from dust, moisture, mechanical shock, and vibration. Softer and more flexible than epoxies and urethanes with the widest temperature range, these silicone rubber compounds are the best choice for high-temperature applications and electronics exposed to thermal cycling. They have excellent electrical insulation and good moisture resistance but poor chemical and abrasion resistance. Also known as RTV (room-temperature vulcanizing).

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.

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. All require a mixer nozzle and gun to dispense.

Tested to meet ASTM E595, a standard used by NASA, these compounds produce almost no volatile emissions that could damage sensitive electronics, even in a vacuum. Light passes through them easily, so they’re ideal for protecting solar cells and fiber optics. Made of silicone rubber, these compounds are softer and more flexible than epoxy and urethane compounds. That means they’re better at protecting against shocks and vibration. They also withstand a wider range of temperatures, so you can use them with electronics that heat and cool rapidly. These compounds are excellent electrical insulators, and they’ll shield your components from moisture and dust. However, they don’t hold up well to chemicals or scrapes. They’re also known as RTV (room-temperature vulcanizing).

These compounds are easy to apply in high volumes. Just mix the two parts together and pour them over components inside a container, such as a potting box.

Thinner than standard potting compounds, these coatings flow easily into small spaces between electrical components. Use them to secure and insulate hardware on printed circuit boards. Rigid and wear resistant, epoxies have excellent chemical and moisture resistance, withstand a wide range of temperatures, and provide excellent electrical insulation. Dispense with a mixer nozzle and a gun (each sold separately).

Handle potted items within minutes—these potting compounds dry quickly when exposed to UV light. For added strength and durability, cure them with heat. Since they’re epoxy, 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. You need a mixer nozzle (not included) and a gun and plunger (both sold separately) to dispense. The nozzle lets you apply these compounds precisely.

For maximum effectiveness, these compounds need to be heat cured after they’re cured with UV light. Overall dry time includes heat curing at 149° F.

These compounds dry quickly when exposed to UV light allowing you to handle the potted items sooner. Made of silicone rubber, they’re softer and more flexible than epoxy or urethane compounds, so they’re better at protecting against shocks and vibration. They also withstand a wider range of temperatures, so they’re often used with electronics that heat and cool rapidly. These compounds are excellent electrical insulators, and they’ll shield your components from moisture and dust. However, they don’t hold up well to abrasion or chemicals. The tapered nozzle lets you apply them precisely.

Protect circuit boards and other electronics from fire and heat. These self-extinguishing compounds meet UL 94V-0 for flame retardance and withstand temperatures up to nearly 400° F. Use them to shield components from dust, moisture, chemicals, mechanical shock, and vibration. Since they’re epoxies, they won’t break down from chemicals or moisture. They’re also excellent electrical insulators. These compounds have the consistency of honey once they’re mixed, so they seep into crevices to encase intricate components.

For invisible bond lines, these adhesives dry clear. Epoxies are the strongest and most chemical-resistant structural adhesives. They bond especially well on metal. Choose an epoxy that hardens quickly for fast repairs, or one that hardens slowly to allow more time for positioning.
