Plasma coating

Plasma coating

With low-pressure plasma, workpieces can be improved with various coatings. To achieve this, gaseous and liquid raw materials are fed into the vacuum chamber. In plasma cross-linking, the raw materials, mostly short-chain monomers, are converted to long-chain polymers. The selection of raw materials then determines the coating properties:

  • Hydrophobic (water repellent)
  • Hydrophilic (water-attracting/wetting)
  • Scratch protection
  • Corrosion protection
  • Carbon coating
  • Barriers/diffusion barriers
  • PTFE-like
  • Frictionless coatings/non-stick coatings
  • Adhesion promoter/primer
  • Water/steam barriers
  • Metallization
  • Nano-silver

Advantages of plasma-coating:

  • Extremely thin coatings are possible on the nanometre scale
  • Series ready, steady processes are possible through full automation
  • Variety of options are feasible
  • No temperature loading
  • No solvents
  • Very good gap penetration properties
  • Suitable for general items and bulk
