Spreader Plate Coating Machine

The scraper film applicator uses an adjustable gap scraper to spread coating materials on a flat substrate, forming a uniform wet film. It is used in laboratories to simulate the roller coating process and test the leveling, hiding power, and coating thickness of paints. It is suitable for quality control in industries such as inks and paper.
Selection
When selecting, consider the substrate thickness range and coating width. The precision of the doctor blade gap adjustment must match the coating thickness requirements. Pay attention to the corrosion resistance of the doctor blade material and the flatness of the substrate. The equipment should have a stable pressure adjustment mechanism. Choose the appropriate model based on the viscosity of the commonly used coating.
