SE-KTQ-500SD 500 mm Wide Slot-Die Film Applicator with Rolling Frame and Digital Micrometer Adjustment
The SE-KTQ-500SD is engineered for laboratory-scale thin film coating applications requiring high precision and uniformity over a 500 mm substrate width. It addresses challenges in maintaining consistent coating thickness by integrating a slot-die applicator mounted on a rolling frame that reduces friction between the substrate and applicator during operation.
This design ensures a stable and controlled coating clearance, which is critical for achieving uniform film deposition. The coating gap can be finely adjusted with an accuracy and increment of ±1 micron using two digital micrometers, allowing precise control of the film thickness. The unit includes sets of stainless steel shims (0.2 mm, 0.3 mm, and 0.4 mm) to facilitate calibration and adjustment of the coating gap.

대표적인 적용 분야
Ideal for research and development of thin film coatings in fields such as electronics, photovoltaics, battery electrodes, and functional coatings where uniform film thickness and minimal substrate disturbance are critical.
구성 및 작동 안내
Optimal coating results depend on careful adjustment of parameters including slurry viscosity, feed rate, coating speed, drying temperature, and shim thickness. The unit is compatible with additional equipment such as flat-bed coaters and syringe pumps for slurry delivery, which are recommended but not included. Operators should ensure proper calibration of the micrometers and maintain the rolling frame wheels for smooth operation.
