TM Super Shield Silver Conductive Coating 842 Technical Data Sheet 842-Aerosol Description The 842 Silver Conductive Coating is a one-part durable acrylic lacquer pigmented with an extremely conductive silver flake, packaged in convenient aerosol format. It utilizes a solvent based system with no heat cure necessary. The cured coating is smooth, hard, and abrasion resistant. It provides good adhesion to plastics, extreme conductivity, very strong high frequency shielding, and extreme corrosion resistance, even in harsh marine environments. Applications & Usages The 842 is designed to provide a conductive coating to the interior of plastic electronic enclosures to suppress EMI/RFI emissions. It excels when the highest level of shielding is required. It is optimal for military, medical, or other mission critical applications where the highest levels of attenuation are essential. The 842 is commonly used by manufacturers of these devices: Medical Equipment Cellphones, laptops, PDAs Military equipment Consumer electronics Scientific equipment Automotive applications Test Equipment Aerospace applications Communication devices Drones and other RC vehicles Other applications for 842 include: Repairing damage to existing shielding Providing electric continuity for circuits Conductive undercoat for electroplating Circuit repair It is a simple effective solution to impart maximum conductivity to a surface. Benefits and Features Meets MIL-STD-883H Provides extreme EMI/RFI shielding over a broad frequency range Volume resistivity of 0.0002 cm ENVIRONMENT Smooth, durable, and abrasion resistant Meets RoHS directive Available in liquid format Low-VOC Quick dry time, no heat cure required 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 7 Rev.
