TM Super Shield Nickel Conductive Coating 841 Technical Data Sheet 841-Liquid Description The 841 Super Shield Nickel Conductive Coating is a one-part durable acrylic lacquer pigmented with a highly conductive nickel flake. It utilizes a solvent based system with no heat cure necessary. The cured coating is smooth, hard, and abrasion resistant. It provides strong adhesion to plastics, excellent conductivity, and strong corrosion resistance, even in marine environments. Applications & Usages The 841 is designed to provide a conductive coating to the interior of plastic electronic enclosures to suppress EMI/RFI emissions. It excels when corrosion resistance is a concern. The 841 is commonly used by manufacturers of these devices: Sensors Networking gear, firewalls Controllers Military equipment Receivers Cellphones, laptops, PDAs Test Equipment GPSs, navigation systems Scientific equipment TVs, monitors, and displays Medical Equipment Consumer electronics Communication devices Electronic sporting equipment Satellite dishes and radar systems Audio equipment Antennas Electric guitars and other amplified Aerospace applications instruments Electric vehicles Drones and other RC vehicles Cable boxes Other applications for 841 include: Repairing damage to existing shielding Providing electric continuity for circuits Conductive undercoat for electroplating Grounding Protecting metal surfaces from oxidation Benefits and Features UL Recognized (File E202609) Tested in compliance with IEEE Std. 299-1997 Provides effective EMI/RFI shielding over a broad frequency range Volume resistivity of 0.0042 cm Smooth, durable, and abrasion resistant ENVIRONMENT Can be applied by spray or brush RoHS Compliant Low-VOC Available in aerosol format Quick dry time, no heat cure required Mild solvent system, safe on polystyrenes Strong adhesion to acrylic, ABS, polycarbonate, and other injection molded plastics Excellent adhesion to wood, ceramics, copper, and aluminum Extremely corrosion resistant, suitable for harsh marine environments Page 1 of 8 Rev.
