Effects of Particle Size


Fine Particles:
  • Lower film builds
  • Can blind cartridges and filters
  • Migrate from part into exhaust
  • Reduced fluidization properties
  • Reduced Farraday penetration
  • Smoother films
  • Absorb moisture more readily
Coarser Particles:
  • Higher film builds
  • Increased Farraday penetration
  • Increased fluidization properties
