Curing methods of hybrid coatings

Thermal curing

  • high temperature (130-160 °C)
  • long curing period (1-2 h) for organic cross-linking reaction (e.g. ring opening of epoxy),  
  • partly inorganic condensation reaction
  • not suitable for many substrates and processes

UV, electron beam curing

  • low temperature method
  • no limitations concerning substrates
  • short curing period for organic cross-linking, e.g. radical polymerization of acrylics
  • suitable for fast in-line processes
  • initiator free curing possible with EB

Low pressure or Atmospher / Pressure plasma

  • low temperature method
  • no limitations concerning substrates
  • no limitations as associated with UV-technol. (O2-inhibition, absorption by pigments) 

Special application areas for UV-curing

  • Protective coatings (scratch resistant, antisoiling)
  • Sensor layers
  • Coatings for glass fibers or sheets
  • UV adhesives
  • Submicronstructured anti-reflective coatings
