coFlex(R) 600 Roll-to-roll web coating machine
The coFlex® 600 vacuum web coating plant can be used to deposit optical, electrical,
and decorative layers on substrates via sputtering techniques and magnetron
PECVD processes. Line speed of up to 100 meters per minute can be achieved.
Potential applications for the coated materials are numerous. Optical layer
systems are, for example, used for UV mirrors and as infrared-reflecting heat
protection layers. Electromagnetic decoupling layers (EMI layers) and
transparent conducting layers are used for displays. Flexible solar cells require
front and back contacts or transparent conducting layers which are applied to
polymer films .
