Super Shield™ Silver Conductive Paint, 150ml Can
842AR is a conductive paint that consists of a 1-part, solvent-based acrylic lacquer, pigmented with an extremely conductive silver flake. It is smooth, hard, and abrasion-resistant. It can be easily applied by brush or spray. It has a quick dry time, with no heat cure necessary. It adheres strongly to most injection-molded plastics, such as ABS, PBT, and PVA. It provides superior high-frequency shielding. It also provides strong corrosion resistance and is suitable for use in marine environments. 842AR is designed to provide a conductive coating for the interior of plastic electronic enclosures that suppresses EMI/RFI emissions. It excels when the highest level of shielding is required. Also, its thin minimum layer height makes it suitable for board-level applications.
