841ER is a 2-part epoxy-based conductive paint, pigmented with highly conductive nickel flake. The cured paint is smooth and extremely hard. It is abrasion, scratch, and mar resistant. It adheres very strongly to most plastics, including chemically resistant and low energy plastics, as well as metal, glass, ceramic and wood.

841ER is generally used either to provide extremely durable corrosion resistant EMI/RFI shielding for applications in harsh environments, or to provide a conductive base layer for electrolytically plating non-conductive plastics.

Features and Benefits
  • Provides excellent EMI/RFI shielding across a broad range of frequencies
  • Resistivity of 3.0 x 10-2 Ω·cm
  • Extreme durability and adhesion
  • Strong chemical, corrosion, and salt fog resistance
  • Wide service temperature range of -40 to 150 °C (-40 to 302 °F)
