MSK-AFA-II-HDS250 Hybrid Film Coater with Slot Die and Doctor Blade
The MSK-AFA-II-HDS250 is engineered to support advanced laboratory coating tasks requiring precise control over film thickness and uniformity. It is particularly suited for developing thin films used in perovskite solar cells, proton exchange membranes for fuel cells, and battery electrode materials. This hybrid coater combines tape coating and slot-die coating capabilities in a single system, allowing researchers to switch between methods depending on experimental needs.
The system incorporates a vacuum chuck made from aluminum alloy with a perforated surface (<1.0 mm holes) measuring 609 mm by 300 mm, which securely holds substrates during coating. The chuck is equipped with a bottom heater controlled digitally to maintain temperatures up to 120°C with ±1ºC precision, facilitating solvent evaporation and film formation. The coating head features a hybrid applicator with a fixed 250 mm wide PTFE doctor blade for tape coating and a removable 200 mm wide slot die head for slot-die coating. Both coating gaps are adjustable with ±1 micron accuracy using dual digital micrometers, enabling fine-tuning of film thickness from as thin as 0.005 mm (slot die) to 0.010 mm (doctor blade).

대표적인 적용 분야
This hybrid film coater is ideal for research and development of thin films in energy devices, including perovskite solar cells, fuel cell proton exchange membranes, and battery electrodes. It supports precise control of film thickness and uniformity necessary for optimizing device performance.
구성 및 작동 안내
The system requires a separate vacuum pump, which is not included and must be ordered independently. The included digital syringe pump offers multiple operating modes such as infuse only, withdraw only, and combinations thereof, facilitating flexible slot-die coating processes. For improved coating quality, controlling slurry viscosity and dispersion is critical; optional viscosity meters and dispersing machines are available separately to optimize these parameters.
The coating gap adjustment with micron-level precision allows for fine tuning of film thickness, but operators should ensure careful calibration and handling to maintain accuracy. The vacuum chuck heating supports substrate temperature control up to 120°C, aiding solvent evaporation and film formation during coating.
