MG Chemicals # 841AR-340G Super Shielding Nickel Conductive Paint, 340 g (12 oz) Aerosol Spray.Shielding paint for plastic enclosures in convenient aerosol spray packaging. It is a solvent based acrylic lacquer, pigmented with a highly conductive nickel flake. Unlike diamagnetic fillers such as carbon, copper, or silver that only shield the electric component of electromagnetic waves, nickel is ferromagnetic and shields the magnetic component as well. It has a quick dry time, with no heat cure necessary. The cured coating is smooth, hard, and abrasion resistant. It adheres strongly to most injection molded plastics, such as ABS, PVC, nylon and polycarbonate. It also provides strong corrosion resistance and is suitable for use in marine environments.
841AR provides broad spectrum electromagnetic shielding. Unlike most conductive paint pigments that only shield the electric component of waves, nickel blocks the magnetic component as well. A 1 or 2-coat application to the interior of the electronics enclosure will solve the EMC issues of most devices. It may also be used as a conductive undercoat for electroplating plastic or creating well grounded surfaces.
This aerosol spray product is also available in liquid and conductive pen formats. We also offer a more economical carbon-based alternative, or a more conductive silver-coated copper version. Before applying this product to plastic, clean the surface with IPA.
