NovaCentrix PSPI-1000® Conductive Aerosol Spray Ink
Categories: Fluid; Other Engineering Material

Material Notes: PSPI-1000 is a water-based silver nanoparticle conductive coating especially produced for EMI / RFI shielding and is designed to thermally cure at low temperatures. This ultra-low VOC sprayable coating is designed for plastic substrates. It provides a very thin film thickness (1 - 3 µm) with excellent shielding properties while being resistant to scratching and abrasion. It is especially useful where VOCs must be limited or when lower curing temperatures are desired.

Key Benefits

  • Excellent flow properties and spray coverage
  • Excellent adhesion to polycarbonate, ABS, and other plastic enclosures
  • Spray coverage 3 - 4 times greater than alternative spray shielding products
  • Minimal VOCs
  • Easy cleanup with soap and water
  • Typical results: 2 µm cured film thickness can be deposited with a single spraying step, 0.2 - 0.8mm² nozzle delivery area, 20 - 30 psi.
