    These coatings protect circuit boards and other electronics from moisture, dust, and static. They’re thinner than potting compounds, so they flow into the smallest contours of your components to cover them completely. Apply these coatings without needing a potting box or other container. You can remove them if necessary.
    Silicone Rubber—Silicone rubber coatings protect components over a wide range of temperatures. They’re also the most flexible of our conformal coatings, so they won’t crack from vibration. However, they’re thicker than acrylic coatings, so they’re more difficult to apply and remove.
    Urethane Rubber—Urethane rubber coatings are the best choice for harsh environments. They have the best chemical resistance in our offering, and they’re extra hard for the best resistance to scrapes. Plus, they won’t crack in low temperatures. However, they aren’t as flexible as silicone coatings, so they’re worse at handling vibration. They’re also harder to apply than acrylic coatings because they’re thicker.
    Bottle—Coatings in a bottle come with a brush for touch-ups.
    Ultraviolet—Coatings with ultraviolet visibility show up under a black light, so you can easily check if you’ve applied them evenly.
    IPC-CC-830—Coatings that meet IPC-CC-830 are certified for use on circuit boards.
    UL 94 V-0—Coatings that meet UL 94 V-0 have passed a test for flame retardance.
    Cannot Be Sold To—Coatings that cannot be sold to the listed areas are restricted due to VOCs (volatile organic compounds) regulations.

    Image of Product. Front orientation. Conformal Coatings. High-Temperature Conformal Coatings.
    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 rubber 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.
    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.
    Cannot Be Sold To—They cannot be sold in California or outside North America due to regulatory limits on VOCs.

    Optically Clear Conformal Coatings

    Image of Product. Front orientation. Conformal Coatings. Optically Clear Conformal Coatings.
    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 rubber, they won’t cloud in hot, humid environments. That means they’re great for use outdoors, such as on signs and instrumentation panels. These coatings are thinner than potting compounds, flowing into the smallest contours on your device to cover it completely. Silicone rubber 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.
    Cannot Be Sold Outside North America—These coatings cannot be sold outside of North America due to regulatory limits on VOCs (volatile organic compounds).

    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 rubber 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.
    UL 94 V-0—Potting compounds that meet UL 94 V-0 have passed a test for flame retardance.
    Cannot Be Sold to California—Potting compounds that cannot be sold to California exceed local regulatory limits on VOCs (volatile organic compounds).
    Cannot Be Sold to Canada—Potting compounds that cannot be sold to Canada are restricted by product labeling requirements.

    Low-Outgassing Optically Clear Two-Part Silicone Rubber Potting Compounds

    Image of Product. Front orientation. Potting Compounds. Low-Outgassing Optically Clear Two-Part Silicone Rubber Potting Compounds.
    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.

    Urethane Potting Compounds for Harsh Environments

    Image of Product. Front orientation. Potting Compounds. Urethane Potting Compounds for Harsh Environments.
    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.

    Cartridge Potting Compounds

    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 rubber, 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 Potting Compounds—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 Potting Compounds—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.

    Urethane Potting Compounds

    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.
