Doctor Blade Bar Coating Machine

The blade Coater with an adjustable gap evenly spreads the coating onto the substrate surface using a doctor blade, forming a wet film with a controllable thickness. It is used in laboratories to simulate coating processes and evaluate the leveling, hiding power, adhesion, and other properties of coatings. It is suitable for the preparation and quality control of coatings on materials such as inks, paper, and plastic films.
Selection
When selecting, consider the substrate type and width to match the Coater specifications. Determine the blade gap adjustment range based on coating thickness requirements, and select the appropriate blade material in combination with the coating viscosity. It is necessary to verify the controllability of the coating speed and ensure that the sample is flat and securely fixed. Prioritize structures that are easy to clean to accommodate the daily switching between various coatings.
