SE-KTQ-4S Four-Sided Fixed Gap Film Applicator with 80/120mm Width and 5-20μm or 50-200μm Coating Thickness Options
The SE-KTQ-4S film applicator is engineered for laboratory applications requiring precise thin film coatings on substrates with minimal material usage. It is particularly suited for small batch coating tasks where consistent film thickness and uniformity are critical. This applicator features four fixed gap paths, enabling simultaneous coating thickness control on multiple sides.
Constructed from stainless steel for durability and chemical resistance, the applicator is available in two width options: 80 mm and 120 mm. The 80 mm version measures 100 mm in length, while the 120 mm version is 140 mm long. Both versions offer coating thicknesses selectable from four fixed gaps of 5μm, 10μm, 15μm, and 20μm on each side, with the 80 mm model also optionally providing thicker gaps of 50μm, 100μm, 150μm, and 200μm. Custom lengths up to 120 mm can be requested to fit specific coating requirements.
Key Features

Typical Applications
Ideal for laboratory thin film coating tasks involving small quantities of slurry or coating material. Commonly used in research and development settings for coating substrates in electronics, battery electrodes, and material science experiments where precise film thickness is essential.
Configuration & Operating Notes
When working with high viscosity slurries, the applicator may tend to float; applying a die weight plate on top using double-sided tape can improve stability. For ultra-thin coatings around 5 microns, use with an automatic coater at slow speeds below 10 mm/min is recommended. Customized traverse pushers are available to maintain consistent coating speed. Additional accessories such as die weight plates and slurry viscosity testers can be ordered separately to optimize coating performance.
