Blade and Rod Film Coater

The wire bar Coater controls the coating thickness through the steel wire wound on the surface of the metal bar. The blade evenly spreads the coating onto the substrate to form a test film layer. It is used in laboratories to simulate the coating process and to test the leveling, hiding power, and drying characteristics of coatings. It is suitable for coating preparation and quality control of materials such as inks, paper, and plastic films.
Selection
When selecting, consider the substrate type and size to match the coating width. The wire rod specifications determine the wet film thickness, which must correspond to the paint viscosity. Adjust the blade pressure smoothly and evenly. The equipment material should have corrosion resistance to adapt to different solvent environments. The operation interface should be simple and convenient for setting film thickness parameters. During maintenance, pay attention to cleaning the wire rod and checking for blade wear.
