SE-KTQ-300SD-A Semi-Automatic 300 mm Wide Slot-Die Film Applicator with Four Rollers and Ar Gas Compatibility
The SE-KTQ-300SD-A is engineered to deliver precise and uniform thin film coatings on substrates by automatically adjusting the clearance between the slot die and the substrate surface. This semi-automatic applicator is ideal for laboratory environments requiring controlled coating processes, including those conducted under inert argon atmospheres within glove boxes.
Equipped with a 300 mm wide slot die mounted on a low-friction rolling stage supported by four wheels, the system ensures smooth and consistent coating application. Two 24V DC motors drive the automatic adjustment mechanism, allowing gap control with an accuracy and increment of ±1 micron, displayed on dual digital micrometers for real-time monitoring.
Key Features
- Automatic gap adjustment between slot die and substrate via two 24V DC motors with micron-level precision.
- 300 mm wide slot die mounted on a rolling stage with four wheels to minimize friction and ensure uniform coating.
- Two digital micrometers provide accurate real-time measurement of the slot die-to-substrate distance.
- Compatible with argon gas environments, suitable for use inside glove boxes.
- Includes stainless steel shims in thicknesses of 0.2 mm, 0.3 mm, and 0.4 mm for fine-tuning coating thickness.
- Operates on a single-phase 110~240V 50/60Hz power supply with low power consumption (2 × 15W motors).

Typical Applications
This applicator is suited for laboratory research and development involving thin film coatings where precise control of coating thickness and uniformity is critical. It is especially useful for coating processes requiring inert atmospheres, such as in glove box environments with argon gas. Typical uses include coating of functional films, battery electrodes, and other advanced material layers.
Configuration & Operating Notes
Optimal coating results depend on adjusting multiple parameters including slurry viscosity, feeding speed, gap between slot die and substrate, shim thickness, coating speed, and drying temperature. The unit includes stainless steel shims for manual thickness adjustment. Additional accessories such as a wider flat-bed coater (>400 mm) and syringe pump are recommended but not included. The device’s compatibility with argon environments facilitates safe operation inside glove boxes.
