Constant Speed Coater

The constant speed Coater moves the substrate at a uniform speed and controls the coating thickness with a blade to form an even coating on the surface of paper or film. It is used in laboratories to simulate coating processes and test properties such as coating adhesion and coverage.
Selection
Select the clamping method based on the substrate thickness, match the blade gap according to the coating viscosity, configure the heating unit in accordance with drying requirements, determine the effective coating width by referencing the sample size, and reserve expansion interfaces for subsequent testing items.
