Conductive Spray Paint

These electrically conductive spray paints for plastic are mostly used as shielding spray paint to prevent electromagnetic interference from penetrating electronics enclosures. They are also used as electroplating spray paint to provide a conductive undercoat in plating applications, as a grounding spray, and to create ESD-safe surfaces. Aerosol packaging allows low volume users to achieve professional quality results without resorting to expensive spray equipment and is convenient for field repairs.

These conductive paints consist of a solvent-based acrylic binder pigmented with either carbon, nickel, silver-coated copper, silver, or ESD-safe pigments. Our acrylic system is flexible, smooth, and durable. It is easy to use and dries quickly at room temperature. The choice of pigments affects the price and performance of the product.  As one moves from carbon to nickel to silver-coated copper to silver, both the price and quality of performance increase. All pigments except silver-coated copper display exceptional corrosion resistance.

These products are also available in liquid and conductive pen formats. If you are looking for a non-conductive protective spray coating, check out our conformal coatings.

  • 1-part system – These coatings are composed of a single-component, simplifying the application process as no measuring or mixing is required. This ease of use minimizes errors during application, ensuring consistent performance and reducing preparation time for users.
  • Easy to apply – The conductive spray paints are designed for turnkey application, requiring no special equipment or expertise, making the process accessible for both professionals and hobbyists.
  • Fast Dry – With a rapid drying time, these coatings help accelerate project timelines by reducing the waiting period between application and handling. This feature is particularly beneficial for high-throughput production environments where time efficiency is crucial.
  • UL registered versions – Some of these conductive paints have UL (Underwriters Laboratories) certification, signifying that they meet rigorous safety and performance standards. This registration provides users with added assurance of product reliability and regulatory compliance, essential for applications in industries where safety is a priority.
  • Excellent adhesion to most plastics – Formulated for superior bonding, these coatings adhere well to a wide range of plastic substrates commonly found in electronic enclosures, including ABS, PVC, nylon, and polycarbonate. This strong adhesion enhances the durability and longevity of the conductive layer, ensuring stable performance over time.
  • Does not contain toluene, xylene, or MEK – The exclusion of toluene, xylene, and methyl ethyl ketone (MEK) from these coatings makes them safer for both the user and the environment. These substances are known for their health and environmental risks, so their absence reduces the potential for harmful exposure and aligns with eco-friendly practices.
  • EMI / RFI shielding for plastic PCB enclosures – These conductive paints are ideal for providing electromagnetic interference (EMI) and radio frequency interference (RFI) shielding in plastic PCB enclosures. By forming a conductive layer, they not only effectively block unwanted electromagnetic signals from interfering with the PCB but also contain the electromagnetic fields emitted by the PCB, ensuring reliable performance and protection of sensitive electronic components.
  • Conductive coating for electroplating – Used as a base layer in electroplating processes, these coatings facilitate the deposition of metals onto non-conductive plastic surfaces. This application is essential for enhancing the conductivity and aesthetic appearance of components used in various electronic and decorative applications.
  • Prototyping and repairing circuits – The versatility of these paints makes them perfect for prototyping and repairing circuits. Whether creating new connections, bridging broken traces, or modifying existing circuit layouts, their ease of application allows for quick and precise adjustments during the design or repair phase.
  • Creating electrical contacts – These coatings can be used to create temporary or permanent electrical contacts, enabling connections where traditional wiring may not be feasible. This capability supports innovative designs in prototyping, wearable technology, and compact electronic devices.
  • Grounding surfaces – Conductive paints are highly effective for grounding surfaces, which is crucial for preventing static buildup and maintaining electrical safety. They can be applied to various substrates to ensure proper grounding in equipment and enclosures, contributing to overall system stability and user protection.
How do I clear a clogged button?

Buttons can become clogged with residual resin not properly cleared. Twist the button off and start with trying to manually free any residue from the button tip using a fine-point tool. You can also soak the button in IPA for a few minutes. To prevent clogging, tip the can upside down and tilt the button upwards at a 450 angle then depress the button until all paint from the valve is dispensed.

How can I prevent coating from getting into unwanted areas?

You can mask unwanted areas using conventional painters tape for flat areas but for more complex, 3D parts, it’s best to use a more conformal product like our 862 peelable solder mask. After applying the final coat, it is important to quickly remove any masking as removing the mask after curing will tear at the edges of the coating, removing it from the substrate.
