Even in furnace-like heat, these coatings protect your electronics from moisture, dust, and static. They withstand temperatures up to 270° higher than standard silicone coatings while remaining flexible enough to not crack and peel from vibration. Whether your circuit board is in a hot, humid shop or inside heavy machinery that heats up and vibrates, these coatings keep it protected. Made of silicone, they won’t cloud from humidity.

Also known as conformal coatings, they’re thinner than potting compounds, so they flow into the smallest contours of your components to cover them completely. Simply spray these coatings on your device without needing a potting box or other container. They contain a UV indicator, so you can use a blacklight to check if they’ve been applied evenly. You can remove these coatings if necessary.

These coatings are IPC certified for use with circuit boards. For flame retardance, they meet UL 94 V-0. They cannot be sold in California or outside North America due to regulatory limits on VOCs.

No mixing required—these potting compounds come ready to apply. 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, silicone potting compounds are the best choice for high-temperature applications and electronics exposed to thermal cycling. They have good moisture resistance but poor chemical and abrasion resistance. Silicones provide excellent electrical insulation. They're also known as RTV (room-temperature vulcanizing) compounds because they don’t need heat or UV light to cure.

Potting compounds that meet UL 94 V-0 have passed a test for flame retardance.

Potting compounds that cannot be sold to California exceed local regulatory limits on VOCs (volatile organic compounds). Potting compounds that cannot be sold to Canada are restricted by product labeling requirements.

Encase electronic assemblies in a layer of silicone for protection from dust, moisture, mechanical shock, and vibration. Softer and more flexible than epoxies and urethanes with the widest temperature range, silicone potting compounds are the best choice for high-temperature applications and electronics exposed to thermal cycling. They have good moisture resistance but poor chemical and abrasion resistance. Silicones provide excellent electrical insulation. They’re also known as RTV (room-temperature vulcanizing).

Cartridge potting compound requires a gun (sold separately) to dispense; use it with the included mixer nozzle.

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 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).

Compounds in a cartridge come with a mixer nozzle for precise application. You need a gun (sold separately) to dispense.

Compounds in a bottle are easy to apply in high volumes. Just mix and pour them over components inside containers, such as potting boxes.

Liquid compounds harden around your component to form a strong, durable, and permanent layer of protection.

Gel compounds form a soft and flexible layer of protection. You can also remove them if you need to re-access your components. They are rated IP68 once potted, so they seal out water even if submersed.

Pot multiple electronics in a flash—these compounds don’t require mixing and they cure within seconds under UV light. Made of silicone, 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.

Make repairs or changes to electrical components after they’ve been potted. While most compounds are permanent, these form a gel that bonds to itself, so you can peel it off without damaging your equipment. Often used in junction boxes, they form a water- and dust-proof seal that’s rated IP68 while also providing excellent electrical insulation. Made of silicone, they withstand a wide range of temperatures and are soft and flexible enough to resist shock and vibration. However, they’re not as strong as permanent potting compounds, so they don’t resist scrapes as well as those made of epoxy and urethane. They’re also not as chemical resistant as epoxy and urethane compounds.

These compounds won’t solidify once you open the container, so you have time to make adjustments when applying them. When removing them from your components, they mostly come off in one piece but there might be some residue left over.

Bottle compounds are a better choice for filling up new enclosures than cartridge compounds because you can pour more in at a time. They have a compartment for each component and require mixing.

Cartridge compounds have a nozzle for precise application. The nozzle can also fit into junction box knockouts, so it’s easier to fill up installed enclosures than it is with bottle compounds. They come ready to use with no mixing required and no waiting time.

Encase electronic assemblies in a layer of urethane for protection from dust, moisture, chemicals, mechanical shock, and vibration. Urethanes withstand a wide range of temperatures and are the best choice for cold-temperature applications. They have excellent flexibility, good chemical and moisture resistance, and provide good electrical insulation.

Cartridge potting compounds can be applied precisely through the included mixer nozzle. You’ll need a dispensing gun (sold separately). US2350™ also require a 4:1 plunger (sold separately) to dispense.

Bottle potting compounds are easier to apply in high volumes than cartridge potting compounds. Mix the compounds together and pour them over components inside potting boxes and other containers. If mixing introduces any air bubbles, put the mixture in a vacuum chamber.

Compounds that cannot be sold to the listed areas are restricted by product labeling requirements.

In just 20 seconds under a UV light, these urethane compounds form into a strong protective layer on electrical components. They withstand a wide range of temperatures and are good electrical insulators. They also stop chemicals, moisture, and dust from damaging your device. With excellent flexibility, they protect against vibration and impact. Since they also work as an adhesive, you can use them to bond and insulate components such as electrical connectors and thermal switches. No mixing required.
