SEKTQ250D-SR Digital Micrometer Adjustable Film Applicator with 250mm Length and PTFE Slurry Slot for Precise Wet Film Coating
The SEKTQ250D-SR film applicator is engineered to deliver consistent and adjustable wet film thicknesses, essential for research applications such as ceramic tape casting and battery electrode fabrication. Its design supports uniform coating distribution, enabling laboratories to produce high-quality films with precise control over thickness.
This applicator incorporates a PTFE slurry slot that spans 180mm in coating width, ensuring even distribution of coating materials ahead of the doctor blade. The device’s stainless steel doctor blade frame is equipped with dual digital micrometer heads, allowing operators to finely adjust blade clearance and achieve wet film thicknesses ranging from 0 to 5000 microns.
Key Features
- Dual digital micrometers with 1″ travel and 0.001 mm resolution for precise thickness adjustment.
- PTFE slurry slot with 180mm coating width for uniform material distribution.
- PTFE components provide high corrosion resistance and thermal stability up to 200°C for short durations.
- PTFE buffering pads reduce friction at the doctor blade’s bottom, enhancing smooth operation.
- Instant inch/millimeter conversion on micrometers for versatile measurement.
