Coating Film Applicator.

The drawdown coating machine applies a uniform layer of wet film on a substrate by evenly spreading the coating material with a blade. It is used in laboratories to simulate the coating process, testing properties such as the leveling and hiding power of coatings. It is suitable for quality control in industries such as inks and paper.
Selection
When selecting a blade coating machine, factors to consider include the corrosion resistance of the blade material, compatibility with the substrate, coating width, and the range of thickness adjustment. Determine the required machine precision based on the viscosity of commonly used coatings, choose an appropriate size according to the available laboratory space, and ensure ease of operation.
