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.

Shield circuit boards from flux, solder, conformal coatings, and high temperatures. Heat resistant up to 640° F, these temporary coatings are most often used to protect open through-holes and components during wave soldering. Coatings can also act as a short-term adhesive to keep parts in place when you’re soldering a two-sided SMT circuit board. An alternative to masking tapes that require cutting to shape, these gel coatings flow easily into small spaces and don’t leave a residue when removed. They’re also known as solder masks. Product regulations restrict sales to the listed jurisdictions/areas.

Choose wash-away coatings if you use a water-based cleaning process such as a batch or in-line cleaning system. Wash-away coatings with a one-hr. overall dry time are nonflammable. They’re not completely water soluble, so they can’t be used in closed-loop cleaning systems. Coatings with a two-hr. overall dry time are completely water soluble for use in closed-loop cleaning systems. They’re slightly flammable.

Choose peel-away coatings if you use a solvent-based cleaning process or don’t clean your circuit boards. Peel-away coatings with a one-hr. overall dry time produce low odors because they don’t contain ammonia.

Hide proprietary information on electrical components while also protecting them from moisture, dust, and static. All it takes is a single thin layer of these black coatings. They’re often used to protect custom parts while prototyping. Place them under a UV curing lamp to fully harden them in just 5 seconds. Made of urethane, they resist chemicals and scratches and won’t crack in low temperatures. That means they’re great for harsh environments. These coatings meet UL 94 V-0 for flame retardance.

Also known as conformal coatings, they’re thinner than potting compounds, so they flow into the smallest contours to cover your parts completely. They also don’t require a potting box or other container. Dispense these coatings with a gun (sold separately).

Protect LEDs, solar cells, and fiber optics with a coating that’s clear enough to see through. These coatings let optimal light pass through and repel dust and moisture, so they won’t distort your view of what’s underneath. Made of silicone, they won’t cloud in hot, humid environments. That means they’re great for use outdoors, such as on signs and instrumentation panels. Also known as conformal coatings, these coatings are thinner than potting compounds, flowing into the smallest contours on your device to cover it completely. Silicone conformal coatings are the most flexible kind of conformal coating, so they won’t crack or peel from vibration. To protect sensitive equipment, these coatings also prevent static discharge.

Simply spray these coatings on your device without needing a potting box or other container. Since they cure at room temperature, you won’t need UV lights or cure ovens either. You can remove them if necessary.

These coatings are IPC certified for use with circuit boards. They also meet UL 94 V-0 for flame retardance. They cannot be sold in California due to local regulatory limits on VOCs.

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.

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 epoxy for protection from dust, chemicals, moisture, mechanical shock, and vibration. The strongest of the potting compounds, epoxies are rigid and wear resistant. 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.

3M DP460EG and DP4XLEG also require a plunger to dispense.

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.

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).

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).

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.

From shore to sea floor, these potting compounds are formulated for permanent submersion in water—even salt water. Use them to protect circuits and splices in pumps, underwater lighting, and other underwater electronics from corrosion and chemicals. Made of urethane, they withstand a wide range of temperatures, especially cold underwater conditions. They provide good electrical insulation and have excellent flexibility. Since they’re more flexible than epoxy compounds, they’re often used to protect against vibration and impact.

Mix the two parts of these compounds together and pour them over components inside a potting box or other container. If mixing causes air bubbles, put the mixture in a vacuum chamber to remove them.

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.
