Product Review

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.UL Recognized (File # E202609). Tested in compliance with IEEE Std. 299-1997. High Conductivity. Tough and durable coating. Stronger adhesion than water based coatings. Low VOC's. Median attenuation 50 dB +/-25 dB per 38 micrometer for frequency range of 10 to 18,000 MHz. Its primary applications are in cell phones, PDA’s, other consumer electronics, telecommunication equipment, industrial equipment, medical devices, military devices, and aerospace equipment. It can also works well on drywall, and can be used to shield entire rooms. 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. RoHS compliant.
