Doctor Blade Bench-Top Coater

The laboratory Coater with a doctor blade platform evenly spreads slurry onto the substrate surface using an adjustable doctor blade, forming a wet film of a specific thickness. It is used to simulate industrial coating processes and evaluate the uniformity of coating coverage and adhesion effects on materials such as paper and films. It is suitable for formula verification and process parameter adjustment during the research and development phase.
Selection
When selecting, consider substrate compatibility, size, and thickness range. The adjustment accuracy of the blade must match the coating thickness requirements. Pay attention to the temperature control stability of the heating platform and the material tolerance. Choose the transmission system according to the coating speed requirements, and ensure the operation interface is simple and easy to maintain.

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?
