Quality improvement of biobased coatings and nanoparticle synthesis
- Application: Consumer goods, Energy & Transport, Packaging
- Development: Formulation, Nano materials
Current status
Biobased and conventional coatings and formulations can be produced in batches in a reactor. Up to 100 l can be stirred, cooled (- 5 °C) and heated (225 °C); evaporation, solvent exchange and filtration are also possible. Due to the normally very low coating thickness, up to 5000 m2 can be coated. In the R2R coating facility, polymer films can be coated by means of slot die. Drying takes place thermally.
Challenge
The challenge in developing the coating formulation is to match the coating to the substrate quality and properties, as bio-based materials in particular have difficult surfaces, low temperature stability and are not stable over time.
The machinability of biobased materials in roll2roll processes is often difficult and the expected cycle rates cannot/hardly be achieved.
Reduction of upscaling time for new lacquer systems due to semi-automatic dosing unit (2l/min) accurate, automatic temperature control (0.1 °C temperature deviation), so that a batch can be produced in 1.5 to 2 days.
Further development
Better quality control during the synthesis.
Application of nanometer thick SiOx-layer in the R2R facility as a pretreatment and an additional barrier layer in combination with the bioORMOCER barrier layer.
Benefits for companies and SME’s
The advantage for customers is the flexibility in synthesis. We can produce, process or modify almost all materials (bio-based or fossil-based). In addition to the technical equipment, the safety technology is also available.
Through our experience, we can also scale up laboratory synthesis, so that we can also scale up developments that have run through third parties. The coating facility is also very flexible and can even process rigid substrates. The equipment (upgrade of the pilot facility) with the SiOX system is unique in the world and offers barrier coatings without the use of vacuum.
