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
