7 Special Note on the operation of the plasma process
7.1 General description
Treating surfaces with atmospheric plasma has several advantages. Examples include the increase of surface
energy resulting in improved surface wetting.
Optimal surface wetting is the first and often decisive step to get a good imprint, a uniform coating, a consistent
coat of varnish or an integrally-bonded application of adhesive. The bond at this boundary layer often
determines the longevity and adhesive strength of this material pairing.
Atmospheric-pressure plasma increases throughput in many industrial processes, while at the same time saving
costs for solvents or chemical primers. We have successfully integrated our plasma products into the following
application fields:
 Cleaning of metal, glass and plastics
 Surface activation and surface functionalization for optimized wettability
 Plasma-assisted laminating process
 Plasma-assisted adhesive bonded joints
 Plugging and sealing
 Plasma induced reduction of metal surfaces
 Chemical-free bleaching of textiles
 Plasma decontamination of fabric
 Handling of food products for quality and shelf life
 Decontamination of thermally-unstable plastics
 Air purification and odour reduction
 Multi-component injection moulding
Practically all technical material classes can be efficiently processed under atmospheric pressure:
 Metals, metal alloys
 Plastics and composite materials
 Glass, ceramics, inorganic composites, natural stone
 Real leather, imitation leather
 Natural fibres, wood, paper
Since the plasma treatment is always just one part of the entire process, it is important to know the overall
influences on the surface properties in order to achieve an optimal result.
Typical influencing factors could be:
 Plasma process: Distance to the substrate, speed, nozzle geometry
 Substrate/ workpiece: Material composition, contamination, electrical conductivity, thermal conductivity,
moisture content
 Workpiece treatment: Contamination before or after the plasma process, the time duration between the
plasma process and the follow-up process
Treatment examples can be requested directly from Relyon Plasma GmbH.
Additional information on applications, as well as publications, can be found on the website
www.relyon-plasma.com.

7.2 Notes on the correct handling of the substrates to be treated
Caution – Electrical voltage!
• Danger from electrical voltage
- Never direct the plasma beam at people or animals.
- Never touch the plasma nozzle or the plasma jet when the device is in operation.
- Never touch the workpiece to be treated or its holder during plasma generation.
- Make sure that no third party comes into contact with the workpiece to be treated
or its holder.
- If electrically conductive materials touch the workpiece to be worked on, these
materials must be grounded.
This applies not only to direct handling of the device, but also to the workpiece to be handled and its holder.
A functional grounding connection is provided on the device for a special form of plasma treatment involving
transferred electric arcs. If you want to use this special application, please contact Relyon Plasma GmbH
directly.
7.3 Carrying out surface treatment
Depending on the type and condition of your substrate, pre-cleaning before the plasma process can improve the
overall outcome.
The effect of the treatment depends on the working distance, treatment time, speed and consistency of
movement as well as the material to be treated.
Ensure that the substrate is not thermally damaged due to movement that is too slow or a working distance that
is too low.
Treatment examples can be requested directly from Relyon Plasma GmbH.
7.4 Measured to take the surface treatment
To achieve an optimal result, it is important that as little time as possible elapse after the plasma treatment and
that the treated surface is not touched or contaminated. Cleaning the surface AFTER the plasma treatment is
not recommended. Since the workpiece can heat up depending on the type and duration of the plasma process,
it may be necessary to allow the workpiece to first cool down first before the next process step is executed in
order to not negatively affect the follow-up process through the introduction of heat (e.g. certain bonding
processes).
Caution – Hot surface!
The workpiece to be treated can become heated up by the plasma process depending on
the process parameters. If necessary, allow the workpiece to cool down before handling it.
