Film Scraper Rod

The film applicator rod is a manual coating tool that controls the thickness of the coating through grooves engraved on the surface of the metal rod. During operation, it is scraped over the substrate, and the grooves transfer a precise amount of coating to form a uniform wet film. It is used for ink opacity testing, coating adhesion evaluation, and printability inspection.
Selection
When selecting, consider the substrate flatness and the viscosity of the liquid to be tested. Use deep-grooved rods for high-viscosity liquids and shallow-grooved rods for low-viscosity liquids. Stainless steel is resistant to solvents, while aluminum alloy is suitable for water-based systems. The groove depth determines the coating thickness, with common specifications ranging from 10 to 200 μm. Ensure the length of the rod covers the width of the sample.
