The 842 Silver Conductive Coating is an extremely conductive acrylic paint designed to reduce electromagnetic or radio frequency interference (EMI/RFI). Long-term protection from EMI/RFI is assured by its durable acrylic resin that minimizes loss of metallization through rubbing, and by the oxidation resistant silver that slows down conductivity degradation with age. The flake shape helps ensure maximum points of contact to ensure better conductivity. In addition, loss of shielding through paint peeling is unlikely since the acrylic resin system was shown, in UL related testing, to adhere to even difficult substrates like ABS and polycarbonates. Its primary application is to provide an excellent-conductivity EMI/RFI shielding suitable for harsh environments. It may also act as a conductive base for applications where it is necessary to impart the highest degree of conductivity to a surface. As well, the silver is non-magnetic, offering a low relative permeability that provides reasonable skin depths, which makes it suitable for microwave transmissions applications.


  • Extremely effective EMI/RFI shielding spray
  • Extreme Conductivity (=15 Siemen)—Low Surface resistance of =0.066 O/sq for a 1 mil coat
  • Median attenuation of 75 dB ±20 dB per 25.4 µm (~1.0 mil) for frequency range of 10 MHz to 18 GHz
  • Tough, durable and Rub off resistant coating. Stronger adhesion than water based coatings. Resists Corrosion
  • RoHS compliant
