Doctor Blade Coating Film Applicator

The blade Coater evenly spreads paint on the substrate surface through a uniformly moving blade, forming a wet film with controllable thickness. It is used in laboratories to simulate coating processes, test the leveling, hiding power, and other properties of paints, and is suitable for quality control in industries such as inks and paper.
Selection
When selecting, consider matching the substrate size to the coating width, ensuring the coating thickness range covers testing requirements, and selecting a blade material that is corrosion-resistant and flat. The motor should operate smoothly with adjustable speed and include a leveling function. Prioritize models that are easy to maintain and have universally compatible accessories.
