    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.
    Cannot Be Sold To—Coatings that cannot be sold to the listed areas are restricted by product labeling requirements.

    Heavy Duty EMI/RFI Shielding Conformal Coatings

    Image of Product. Front orientation. Conformal Coatings. Heavy Duty EMI/RFI Shielding Conformal Coatings.
    Coat electronics for durability in tough conditions while blocking EMI/RFI signals. Made of epoxy mixed with silver-coated copper, these coatings are stronger than acrylic plastic EMI/RFI coatings. They are rigid enough to withstand the wear of access panels and industrial cabinets. You can also use them in engine compartments because they resist damage from high temperatures and chemicals. Also known as conductive paint, they shield your parts from interference that could cause circuit malfunction and data loss. Mix the two parts of these compounds together and paint them on components.
    Cannot Be Sold to Canada— These coatings cannot be sold to Canada due to product labeling requirements.
