Electric Blade Coater

The electric blade Coater uses a motor to drive the blade to move uniformly across the substrate surface, evenly spreading the coating to a specified thickness. It is used in laboratories to simulate coating processes, test the leveling, hiding power, and coating uniformity of paints, and is suitable for sample preparation of materials such as paper and films.
Selection
When selecting, consider matching the substrate width to the coating range, the coating thickness corresponding to the adjustment accuracy of the blade, and ensuring the motor is stable without fluctuations. Choose the blade material based on the viscosity of the material, using stainless steel blades for corrosive liquids. Additional functions such as heating plates should be configured according to drying requirements.

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.
What are some cost-effective alternatives to roll-to-roll coaters for the early stages of flexible film R&D when the investment is too high?
The investment in roll-to-roll coating machines is too high. What are some cost-effective alternatives for the early stages of flexible film research and development? Among blade coating, spin coating, and spray coating, which one would you choose?
