The 842 Silver Conductive Coating is a one-part durable acrylic lacquer pigmented with an extremely conductive silver flake. It utilizes a solvent based system with no heat cure necessary. The cured coating is smooth, hard, and abrasion resistant. It provides good adhesion to plastics, extreme conductivity, very strong high frequency shielding, and extreme corrosion resistance, even in harsh marine environments.

Applications & Usages

The 842 is designed to provide a conductive coating to the interior of plastic electronic enclosures to suppress EMI/RFI emissions. It excels when the highest level of shielding is required.

Its effectiveness at high frequencies and thin minimum layer makes it suitable for board level applications in miniaturized electronics.

It is optimal for military, medical, or other mission critical applications where the highest levels of attenuation are essential.

The 842 is commonly used by manufacturers of these devices:

  • Medical Equipment
  • Military equipment
  • Scientific equipment
  • Test Equipment
  • Communication devices
  • Cellphones, laptops, PDA’s
