Super Shield Silver Coated Copper Conductive Coating (843)




We are a giant Supplier of Super Shield Coated Copper Conductive Coating (843). The 843 Silver Coated Copper Conductive Coating is a highly conductive acrylic paint, which is designed to reduce the 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, the 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.

 

Features :

  • High Conductivity Low Surface resistivity of 0.21 /sq. for one coat (1.0 mil)
  • Tough and durable coating
  • Rub off resistant
  • Corrosion resistant coating
  • Stronger adhesion than water based coatings
  • Low VOC's
  • Median attenuation 60 dB ±18 dB per 25.4 ¼m (~1.0 mil) for frequency range of 10 MHz to 18 GHz


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 the microwave transmissions applications.


Compatibility:

  • Chemical -the silver coated copper is quite resistant to oxidation, except in environments that contain contaminants like H2S or ozone which tarnish its surface
  • The thermoplastic resin is dissolved by common paint solvents like toluene, xylene, acetone, and MEK. This allows great coating repair and work characteristics, but it does make the coating unsuitable for solvent rich environments.
  • Adhesion - The 843 coating adheres to most plastics used to house 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.
