CDZHLTG High-Precision Adjustable Film Applicator Film Preparation Device 0-3500μm

Place the applicator on a completely flat test surface. Adjust the scraper to the required gap; it should be twice the required wet film thickness. Pour a small amount of test sample between the end plates in front of the film knife. At a slow and even speed, about 1-2cm per second. Move the instrument over the surface until the liquid has been fully applied and/or any remaining liquid has been removed from the end of the coating path. The exact ratio of wet film thickness to any coating knife gap depends on the material used, the viscosity and texture of the liquid, the force applied to the coating knife, the coating speed, and the geometry of the coating edge. The actual wet film applied should be measured using a wet film thickness gauge and the gap adjusted until the desired wet film thickness is achieved.
