    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.
    Acrylic Plastic—Acrylic plastic coatings are our thinnest option, so they’re the easiest to apply. They’ll also come off the easiest when you have to rework or repair your component—just use a solvent. These coatings dry in a day or less.
    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.
    Silicone/Acrylic Plastic—Silicone/acrylic plastic coatings combine the flexibility and temperature resistance of silicone with the thinness of acrylic for easy application. Use them in the environments you’d use silicone coatings, such as high-vibration and high-temperature areas.
    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.
    Pen—Coatings in a pen are best for precise application. Use them to repair scratches and chips on components, or touch up areas you missed while coating. They’re also good for blocking off areas you don’t want solder to flow into.
    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.

    High-Temperature Conformal Coatings

    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

    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 Canada—Potting compounds that cannot be sold to Canada are restricted by product labeling requirements.

    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 rubber, 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.
    These coatings are 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 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.
    Cartridge—Cartridge compounds dispense through a mixer nozzle for precise application. Use them with a dispensing gun.
    Can—Can compounds are easier to apply in high volumes than cartridge compounds. Mix them together and pour them over components inside containers, such as a potting box. If you see air bubbles after mixing, put the mixture in a vacuum chamber to remove them.
    Cannot Be Sold to Canada—These compounds cannot be sold to Canada.

    Epoxy Potting Compounds

    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.
