Fraunhofer-Institut für Silicatforschung ISCThermal 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
Curing methods of hybrid coatings
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
