The 843 Silver Coated Copper Conductive Coating is a highly 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. 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.

Applications & Usages

Its primary application is to provide a reasonable cost, high-conductivity EMI/RFI shielding. It may also act as a conductive base for low temperature electroplating processes or for any other manufacturing processes where it is necessary to impart conductivity to a surface. As well, the silvered copper powder is non-magnetic, offering a low relative permeability that provides reasonable skin depths, which makes it suitable for microwave transmissions applications.
