Scraper Proofing Machine

The blade Coater uses a motor to drive the blade to move evenly over the substrate, applying the coating uniformly to form a film of standard thickness. It is used in laboratories to simulate coating processes and test the leveling, hiding power, and color effects of coatings. It is suitable for small-batch sample preparation in industries such as inks and paints.
Selection
When selecting a scraping Coater, it is essential to consider the alignment of the coating width with the substrate dimensions, ensure that the blade gap adjustment range covers the required coating thickness, and guarantee motor stability for uniform coating. Choose between manual or automatic models based on the sample viscosity, and pay attention to the compatibility of the substrate fixtures and the ease of cleaning.
