    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.
    Sprayon—Sprayon acrylic plastic coatings dry in just 30 minutes, the quickest of our conformal coatings. They resist grease, oil, and alkalies. Ideal for metal parts, they prevent rusting. Along with circuit boards, they’re often used on batteries.
    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.

    High humidity, harsh chemicals, water submersions, and salt are no match for these electronic coatings. They also resist UV light, so they’ll work outdoors. Use them on circuit boards, sensors, and LED drivers in heavy machinery. They’re thinner than potting compounds, so they flow into the smallest contours of your components to cover them completely.
    PVDF—PVDF coatings are more flexible than epoxy coatings. They’re IPC certified for use on circuit boards. You can also use them to protect against corrosion on metal joints. To apply, brush or spray them on, or dip your components in.
    Epoxy—Epoxy coatings resist impact and wear better than PVDF coatings, and they work in higher temperatures. You can also use them as an adhesive. For controlled pouring, they’re thickened with silicate. These coatings are autoclavable, and they’ll even cure underwater. Dispense them with a mixer nozzle and a gun (each sold separately).

    Parylene Conformal Coatings

    Image of Product. Front orientation. Conformal Coatings. Parylene Conformal Coatings.
    Protect sensitive electronics at the molecular level—these ultra-thin, ultra-conformal coatings cover every inch of your components for applications where failure isn’t an option. They’ve even been trusted on satellites and medical devices. Use them to insulate current, prevent arcs and short circuits, and shield against moisture, chemicals, and gases. They’re better insulators than epoxy, urethane, and silicone coatings. Deposited as vapor in a vacuum chamber, they’re 90% lighter than spray and dip coatings. That means they’ll keep your items lightweight and won’t damage complex geometries. These coatings meet ASTM E595, a standard used by NASA, so they produce almost no volatile emissions that could damage sensitive electronics, even in a vacuum.
    Note: These coatings must be applied using special parylene deposition equipment.
    Parylene C—Parylene C coatings are the most widely used. They contain chlorine, so they shield against moisture, chemicals, and corrosive gases better than Parylene N coatings. Plus, they’re stronger and quicker to apply.
    Parylene N—Parylene N coatings are better electrical insulators than Parylene C coatings. They also penetrate deeper into crevices on your components for more complete coverage. However, they’re slower to apply.

    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).

    EMI/RFI Shielding Conformal Coatings

    Image of Product. Front orientation. Conformal Coatings. EMI/RFI Shielding Conformal Coatings.
    Protect sensitive electronic parts, enclosures, and prototypes from electromagnetic interference (EMI) and radio frequency interference (RFI) with these coatings. Also known as conductive paint, these coatings block EMI and RFI from disrupting electrical, data, and radio signals, which can cause circuit malfunctioning and data loss.
    For best adhesion, apply to clean, oil-free surfaces. If applying to highly chemical-resistant plastics such as PVC and PTFE, use a primer first.
    Carbon Acrylic Plastic—Carbon acrylic plastic coatings are made with ground carbon powder mixed with acrylic. They're best for RFI and low-frequency shielding applications, such as protecting jumpers and resistors in initial prototypes, since they're not as conductive as nickel and silver acrylic plastic coatings. They don’t contain metal, so they’re also great for electronics where metal-filled coatings could cause malfunction, such as metal detectors.
    Nickel Acrylic Plastic—Nickel acrylic plastic coatings are made with nickel flakes mixed with acrylic. They’re the best in our offering for protecting magnetic components, since they absorb and redirect magnetic fields. While not as conductive as silver acrylic plastic coatings, they still protect against a broad spectrum of EMI and RFI frequencies. Use them to repair small circuits on circuit boards and to coat devices such as meter and scanner housings. They have good corrosion resistance.
    Silver Acrylic Plastic—Silver acrylic plastic coatings are made with silver flakes mixed with acrylic. They’re the most conductive coatings in our offering, so they protect against the broadest spectrum of EMI and RFI frequencies. They’re also the most corrosion resistant. Use them to coat portable electronics, access panels, industrial cabinets, and engine control modules.
