Applications

  • surface pre-treatment prior to bonding and welding processes
  • fine cleaning
  • activation of polymer surfaces
  • generation of hydrophobic polymer coatings at the surface (corrosion protection, scratch resistance)
  • generation of hydrophilic polymer coatings at the surface (improvement of adhesion)
  • generation of barrier coatings
