The wet coating of polymer films and other flexible substrates and their modification allows these materials to be used in a wide range of products. Roll-to-roll plants allow coatings to be efficiently applied at favorable cost.
With the new coating line atmoFlex 1250 (manufactured by 3D-Micromac GmbH, Germany) optical and decorative functional layers, abrasion resistant layers and structured layers manufactured by embossing processes can be applied. The maximum web speed of 150 m/min ensures highly productive coating processes. Wet and dry lamination processes are also possible with the atmoFlex 1250.
The wet coating takes place through a 1.2 m wide slot-die, ensure highly uniform layers in web and cross-web direction. The crosslinking of lacquers will be done by means of an electron beam system. This system may be used also for post-curing of polymers or sterilization of polymer webs or textiles.
All rollers within the atmoFlex 1250 are optimized regarding diameter and surface to handle pre-coated materials properly. Therefore vacuum coated materials maybe processed without altering the thin and delicate vacuum layers.
The atmoFlex 1250 enables Fraunhofer FEP to provide a complete in-house process chain for research and development of multilayer systems, made by wet and vacuum coating processes at industrial scale.
