The 841 Super Shield Conductive Coating reduces electromagnetic or radio frequency interference (EMI/RFI), an issue for all electronic devices. It is a durable acrylic coating pigmented with a high purity  nickel flake, and is UL approved for adhesion to ABS and polycarbonates at hot and cold temperatures.

It is designed to be applied to the interior of plastic electronic enclosures, and is a simple way to deal with EMI/RFI issues, allowing devices to pass FCC emission testing.

841 Aerosol
Product must be vigorously shaken (approx. 2 minutes AFTER you hear the marble inside) prior to use, and periodically during use. After use, invert can and spray to clear nozzle prior to storing.

Adhesion—The 841 coating adheres to ABS, PBT, and most materials found on printed circuit assemblies; however, it is not compatible with contaminants like water, oil, and greasy flux residues that may affect adhesion. If contamination is present, clean the surface to be coated first.
