Laboratory Blade Coating Tester

The laboratory blade Coater test machine uses a motor to drive the blade to move at a constant speed, forming a uniform coating on the substrate surface. It is used to simulate the coating process and test the leveling, hiding power, and film thickness of coatings. It is suitable for quality control and process development of materials such as inks and paper.
Selection
When selecting, consider the compatibility of the substrate thickness with the coating gap, ensure the coating thickness range covers the testing requirements, and choose a blade material that is corrosion-resistant and flat. The motor should have stable and adjustable speed, and the equipment structure must be sturdy and easy to clean. Refer to the sample dimensions to select a worktable area of appropriate size.
