Doctor Blade Film Coating Machine

The film applicator evenly spreads the coating onto the substrate surface using a blade to form a smooth film. It is used in laboratories to prepare coating samples, simulating the industrial coating process, and is suitable for testing the coating performance of materials such as paper and plastic films.
Selection
When selecting, consider the coating width and thickness range to match the sample size. The material of the blade should be compatible with the corrosiveness of the coating. The substrate clamping method ensures flatness, speed adjustment meets the requirements of coatings with different viscosities, and ease of cleaning and maintenance impacts usage efficiency.
