838AR Aerosol TM Total Ground Carbon Conductive Spray Paint 838AR is an economical conductive paint that consists of a 1-part, solvent-based acrylic lacquer, pigmented with highly conductive carbon powder. It is smooth, durable, and abrasion resistant. 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 strong corrosion resistance and is suitable for use in marine environments. 838AR is excellent for creating grounded surfaces and in low frequency RFI shielding applications, such as pickup cavities on electric guitars. It is also perfect for shielding metal detectors and other devices where a metal- filled conductive paint would cause malfunction.

Store between -5 and 40 C in a dry area, away from sunlight (see SDS). 5. Rotate the board 90 and spray again to ensure good coverage. 6. Apply additional coats until desired thickness is achieved (go to step 3). 7. Let dry 3 min at room temperature before applying heat cure. 8. After use, clear the nozzle by inverting the can and briefly spraying until clear propellant comes out.
