Blade Coating Rod Film Applicator

The drawdown bar Coater forms a uniform wet film by rolling a cylindrical bar over the substrate surface, spreading the coating material. It is used in laboratories to simulate the coating process and test properties such as leveling and hiding power of coatings. It is suitable for quality control in industries such as inks and paper.
Selection
When selecting, consider the substrate type and size to match the rod length, and choose coating rods with different groove depths based on coating thickness requirements. Pay attention to the wear resistance of the rod material and the precision of linear motion to ensure uniformity of the coating. The operating environment must meet the drying time requirements of the sample.
