Adjustable Thickness Laboratory Coater

The adjustable thickness laboratory Coater controls the gap between the blade and the substrate through a precision mechanical structure to form a uniform wet film. It is used to simulate the coating process in industrial production, testing the leveling, hiding power, and other properties of coatings at different thicknesses during the research and development stage. It is suitable for the preparation of thin layers of liquid materials such as inks and adhesives.
Selection
When selecting, it is necessary to match the material viscosity with the coating speed range, consider substrate compatibility and the maximum coating width. Pay attention to the corrosion resistance of the blade material, and ensure that the thickness adjustment accuracy meets experimental requirements. The equipment should have a stable substrate clamping mechanism and a clear thickness scale to facilitate repeated operations.
