Device for surface activation and hydrofilization

1. Radio FrequencyScanner

2. Modern trends and challenges
New Material and Coatings development:
1. Composites – space, automotive, aviation, constructions
2. Protective, anticorrosive coatings
3. Functional films
4. Flexible printed circuit boards
Challenge: low adhesion level

3. • Chemical/Electro-chemical methods – toxic, product utilization problem,
high specialization, inertness, multistep processing
• UV-treatment – low intensity, ozone generation
• Plasma methods
• Low pressure – high cost, high result
• Ion gun
• Plasma treatment
• Atmospheric methods – cheap, lower intensity
• Corona/Dielectric Barrier Discharge – low stability, large areas,
high power consumption
• RF Jet treatment – high stability, small areas

4. Plasma surface treatment leads to:
• Dirt, dust, oil removal
• Sterilization (due to UV-generation)
• Relief complexity increase
• Functional groups formation (OH-, COC-, CH3- etc.)
Benefits:
• Unselective process – can be applied to metals, plastics,
glass, others
• Controlled treatment intensity
• Eco-friendly technology
• Better precision (against chemical methods)
Less defect rate, the protective coating is much more stable, it
is possible to use unique combinations of materials, with the
exception of primer, etc.
Trend: plasma activation usage.Why?
