MG Chemicals 841AR -340G - Super Shield Nickel Conductive Spray Paint

Super ShieldTM Nickel Conductive Spray Paint 841AR is a conductive paint that consists of a 1-part, solvent-based acrylic lacquer, pigmented with a highly conductive nickel flake. It is smooth, hard, 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, PVA and ABS/PC blend. It also provides strong corrosion resistance and is suitable for use in marine environments.

841AR provides a conductive coating for the interior of plastic electronic enclosures that suppresses EMI/RFI emissions. It excels when corrosion resistance is a concern.

Applications & Uses

Application Method
Compatible Substrates & Surfaces
Recommended Preparation
Clean the substrate with Isopropyl Alcohol, MG #824, so the surface is free of oils, dust, and other residues.
Application Instructions
  1. Shake pen vigorously until the ball moves freely inside.
  2. Hold pen at angle and depress tip against surface.
  3. Draw pen across surface while gently squeezing barrel.
  4. Let dry 1 min before handling or heat cure.
  5. Clean tip, replace cap and store tip up after use.
Application Instructions
  1. Shake the can vigorously.
  2. Spray a test pattern to ensure good flow quality.
  3. Tilt the board at 45° and spray a thin, even coat from a distance of 20–25 cm (8–10 in). Use spray-andrelease strokes with an even motion to avoid paint buildup in one spot. Start and end each stroke off the surface.
  4. Wait 3 min before applying another coat, to avoid trapping solvent.
  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.
