Automatic Doctor Blade Coater

The automatic blade Coater uses a motor to drive the blade to move uniformly across the substrate surface, spreading the coating evenly to form a wet film of a specified thickness. It is used in laboratories to simulate industrial coating processes and to test properties such as the leveling and hiding power of coatings. It is suitable for the preparation and quality control of coatings on materials such as inks, paper, and films.
Selection
When selecting, consider matching the substrate size to the coating width, and ensure the coating thickness range covers testing requirements. Focus on the corrosion resistance and precision of the blade material, as the motor type affects speed stability. Compatibility with sample thickness and viscosity is essential, and the operation interface should be clear and straightforward. Maintenance convenience and safety features must be verified in practice.

Articles

How to choose a laboratory coater? Which one should you buy: wire bar, scraper, or slot die?
This article introduces three methods for selecting laboratory coating machines: wire bar coating is suitable for low-viscosity coatings, offering low cost and simple operation; blade coating is ideal for medium-to-high viscosity slurries or those containing particles, with a wide range of film thickness control; slot-die coating provides the highest precision and is suitable for high-end applications such as electronic films.
Comparison of Coating Accuracy between Laboratory Blade Coater and Slot Die Coater
This article compares the coating precision of blade coaters and slot-die coaters in the laboratory. Blade coaters are suitable for thick coatings, with simple operation but relatively large uniformity errors; slot-die coaters offer higher precision and better uniformity for thin coatings. The choice of equipment depends on coating thickness and precision requirements.
How to Coat High-Viscosity Slurry – Parameter Setting Tips for Blade Coaters
This article primarily discusses the parameter setting techniques for high-viscosity slurries on blade coaters. High-viscosity slurries exhibit characteristics such as shear thinning, so it is essential to leverage shear effects during coating to facilitate slurry spreading. After coating, the viscosity should recover quickly to prevent sagging.
