Frame Wet Film Applicator

A frame-type wet film applicator consists of a metal frame and a blade, which is used to form a wet film of fixed thickness on a substrate through scraping. Its principle involves controlling the deposition amount of coating material through the gap in the frame, making it suitable for simulating coating processes in the laboratory, testing coating uniformity, and evaluating drying performance. It is applicable for quality control tasks such as ink opacity testing and observation of coating leveling properties.
Selection
When selecting, consider matching the substrate size to the applicator width, and determine the thickness specifications according to the testing standards. Stainless steel material resists solvent corrosion, and keep the blade perpendicular to the substrate during operation. The wet film thickness is directly determined by the frame gap, so verify the nominal value against actual requirements. Clean the gap promptly after use to avoid clogging, and prevent collisions or deformation during storage.
