Scraper Bar Integrated Coating Tester

The integrated blade-and-wire rod Coater controls coating thickness with an adjustable blade and uses wire rods of different diameters to form a uniform wet film on substrates. It is designed to simulate blade coating processes, test properties such as leveling and hiding power of coatings, and is suitable for laboratory coating sampling and printing ink coating tests.
Selection
When selecting, consider the compatibility between the substrate thickness range and the coating width, ensure the blade pressure is adjustable and stable, and make sure the wire rod specifications cover common coating weight requirements. Pay attention to the corrosion resistance of the machine's materials, a user-friendly operation interface, and the inclusion of a calibration certificate. Choose an appropriate gap accuracy based on the viscosity of commonly used coatings to ensure a repeatability test error of less than 5%.
