The 841WB Super Shield™ Water Based Nickel Conductive Coating is a one-part urethane system pigmented with highly conductive nickel flake. It is easy to use, with no let-down, and no heat cure necessary. It can be applied by spray, brush, or roller. The cured coating is smooth, durable, and adheres well to plastics, wood, metal, and ceramics. It also bonds well to drywall and can be painted over with common architectural paints.

Applications & Usages

This coating provides effective EMI/RFI shielding across a broad range of frequencies in architectural and electronic applications.

Water based conductive paints are the only choice for architectural RFI shielding applications because VOC regulations prohibit the use of solvent based systems. Such applications include containing RFI within a room such as an engine room to prevent interference across other rooms. Also, it can be used to protect a room containing sensitive electronic equipment from general sources of interference, such as server rooms, recording studios, laboratories, and surgical rooms, especially those near cell phone or radio towers.

This product is also great for providing EMI/RFI shielding to electronic enclosures, sensors, test equipment, portable controllers, communication devices, and most applications where one would normally use solvent based shielding.

This product also good for repairing conductive traces, and electronic prototyping.
