The pilot coater LabCo

Since 2010 KROENERT offers with the LabCo a line specifically for the development and small batch production of different products. This modular narrow web line was designed to complement the proven RECO and PAK series, and its success has shown that the idea was right. The LabCo has become, in the shortest of times, a bestseller.  

Its modular design makes the machine very flexible, and KROENERT can adapt it to your individual task requirements.  All production parameters can be transferred directly to the RECO and PAK, making the LabCo particularly attractive as a test line and for troublefree upscaling from laboratory to fabrication. 

Its applications are diverse and range from composite technology, pressure sensitive and laminating adhesives, lithium-ion batteries, fuel cells, organic photovoltaics to printed electronics.
