Precision Blade Coater

The precision blade Coater forms an accurate gap between the blade and the substrate to control the thickness of the coating for uniform application. It is used in laboratories to prepare thin film samples and simulate industrial coating processes in applications such as paints and paper surface treatment.
Selection
When selecting, consider the compatibility of the substrate thickness range and coating speed with the equipment parameters. The blade material should be resistant to the corrosiveness of the coating, and the equipment must have a gap micro-adjustment function. Pay attention to the data on coating uniformity and repeatability, and choose between a benchtop or floor-standing model based on the available laboratory space.

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.
