In an inert nitrogen atmosphere with a reduced oxygen content, better crosslinking results can be achieved with a lower photo initiator content than in air.
The monitoring and control of UV radiation and the residual oxygen content in the UV curing area guarantee a stable printing process and thus a consistently high product quality.
Coatings get better under nitrogen. They become more scratch-resistant and more durable. They become more glossy or dull, just as you wish.
Print speeds are increasing. Migration is decreasing. Surfaces can be brilliantly shiny or elegantly matt.
Examples of use:
- Foils (PP/PET/PE/PVC)
- PVC flooring
- Adhesive tapes
- Cigarette packaging
- Release paper
