HDS150PEEK Hybrid Film Applicator with 150mm Doctor Blade and 100mm PEEK Slot Die Head for Precise Thin and Thick Film Coating
The HDS150PEEK is a versatile hybrid film applicator designed to meet the demands of laboratory-scale coating processes requiring both thick and thin film applications. It is particularly suited for producing films used in battery electrodes, perovskite solar cells, and fuel cell membranes. This applicator integrates two coating methods—tape coating via a doctor blade and slot die coating—allowing users to switch between techniques depending on the film thickness and uniformity requirements.
The applicator features a 150 mm wide stainless steel doctor blade equipped with dual micrometers, enabling precise adjustment of film thickness within a range of 0.01 mm to 5 mm. This setup is ideal for thicker slurry-based coatings. For thin film applications, the device includes a 100 mm wide slot die head made from Poly Ether Ether Ketone (PEEK), a semicrystalline thermoplastic known for its excellent mechanical strength and chemical resistance at elevated temperatures. The slot die head facilitates coating thicknesses from 0.005 mm to 0.02 mm, providing fine control over thin film deposition.
Key Features
- Hybrid design combining a 150 mm stainless steel doctor blade and a 100 mm PEEK slot die head.
- Doctor blade thickness adjustable from 0.01 mm to 5 mm using dual micrometers with ±0.001 mm accuracy.
- Slot die head supports thin film coating from 0.005 mm to 0.02 mm thickness.
- Includes PTFE buffering pad under the doctor blade to minimize friction during coating.
- Slot die head comes with shims of 0.2 mm, 0.3 mm, and 0.4 mm thickness for fine gap adjustment.
- Compatible with all brands of flat coating machines and removable slot die for tape coating use.
- PEEK material slot die offers superior chemical and thermal resistance for demanding coating environments.

Typical Applications
This hybrid film applicator is ideal for laboratory research and development involving slurry-based coatings for battery electrodes, thin films for perovskite solar cells, and membranes used in fuel cells. Its dual coating capability allows flexible experimentation with film thickness and uniformity on various substrates.
Configuration & Operating Notes
The slot die head is removable to allow switching between tape coating and slot die coating modes. Optional slot die heads with widths of 10 mm or 50 mm can be installed upon request. For slot die coating, a syringe pump or similar fluid delivery system is recommended to ensure consistent slurry flow through the slot die. The applicator is compatible with all brands of flat coating machines and is especially suited for use with flat surfaces exhibiting high flatness (±2 microns) to achieve uniform coatings.
