      plasma processing uses


      Adding chemical groups with atmospheric pressure plasma highly increases adhesion strength between glued surfaces. The process can be used on almost all materials. Advanced process recipes solve difficult situations.

      Mechanical tests demonstrate 10 times increase of the adhesion strength between assembled surfaces. Atmospheric pressure plasma treatments are the guarantee of high-performance and long-lasting bondings.

      AcXys Technologies equipment deliver the best results according to your specifications.

      Atmospheric pressure plasma surface activation brings strong adhesion of modern inks on the most hydrophobic surfaces without imposing a printing technology.

      Printing on polymers ( Polypropylene, Polycarbonate, Polyethylene, PVC, ...) glass objects or metallic surfaces is trouble-free and immediate.

      AcXys Technologies equipment is easy to integrate on a production line. They are the correct solution for fast production and high quality environments.
      The technology is clean, works in open air without damaging treated surface. Atmospheric pressure plasma is the right process before printing.

      Varnishing and painting

      Atmospheric pressure plasma quickly removes organic contamination from oil or grease used in manufacturing operations and activates surfaces in one process step. Increase in surface energy promotes better wettability and adhesion.

      Paints or varnishes applied on a prepared surface strongly adhere to it. Atmospheric pressure plasma process increases the time before the first signs of corrosion appear in a saline mist test by up to 30% when compared to a wet process.

      Cleaning and decontamination

      Atmospheric pressure plasma is extremely efficient for cleaning surfaces and removal of native metal oxides. The plasma reacts with the non-desirable molecules on the surface without changing or damaging the substrate.

      AcXys Technologies equipment is powerful, easy to utilize and their integration is immediate.

      Barrier layer

      A thin layer of silicon oxide (SiO2) acts as a diffusion barrier on the surface. Atmospheric pressure deposition rapidly applies uniform thin coatings on any surfaces. This layer impedes the diffusion of gases (CO2, O2) through plastics and delays interactions between solids and liquids.

      Scratch resistance

      Atmospheric pressure plasma hard coating deposition is an exciting alternative to other processes for the very demanding applications. Protective layers are deposited evenly on heat-sensitive materials with a simple fast process. Coatings can be applied locally or on the entire surface.

      Self cleaning

      Thin coatings of titanium oxide (TiO2) can be deposited with atmospheric pressure plasma technology. The coating has interesting self-cleaning properties against organic contamination. When the protected surface is in contact with air, combined action of UV and water vapor decomposes continuously all organic pollutant and maintains the surface clean.

      Optical layer

      Deposition of ultra-thin uniform films of silicon oxide over a surface is easily performed with atmospheric pressure plasma. The process is done close to room temperature and does not require pumps and vacuum vessels. 3-D parts are easily processed with appropriate handling.

      Process operation is fast and cost-effective.

      Silicon oxide layers are deposited at temperatures lower than 100 °C. Their optical properties are very close to fused silica. Heat-sensitive polymers or fabrics are processed safely. There are plenty of innovative applications in the field of optical components, mirrors, telescopes and photovoltaic cells.

      Powder processing

      Combination of atmospheric pressure plasma with fluidized-bed technology results in an outstanding process for treatment of powders and nano-particles. Surface energy is increased and powders are easily dispersed in water solutions. The process is incredibly efficient for hydrophilic polymer powders. After a short plasma exposure, they blend instantly in water and make a homogenous solution.
