843ER is a two-part epoxy-based conductive coating, pigmented with highly conductive silver-coated copper flake. The cured coating is smooth and extremely hard. It is abrasion, scratch, and mar resistant. It adheres very strongly to plastics, including chemically resistant and low energy plastics, as well as metal, glass, ceramic and wood.

843ER is generally used either to provide extremely durable EMI/RFI shielding for applications in harsh environments, or to provide a conductive base layer for electrolytically plating non-conductive plastics.
