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
