Coating sample Rod

The coating applicator rod is a tool with specific depth grooves engraved on the surface of a metal or plastic rod body. Its principle involves using the grooves to control the formation of a uniform wet film of the coating on the substrate. It serves the purpose of providing standardized coating thickness samples for laboratories and is applied in industries such as inks and coatings for quality comparison and drying tests.
Selection
When selecting, consider the substrate flatness and the viscosity of the material to be measured. Wide-groove coating bars are suitable for high-viscosity materials. Determine the groove depth based on testing standards, with common specifications ranging from 25 to 200 micrometers. Note that the hardness of the coating bar material must be higher than that of the substrate. Stainless steel is suitable for most scenarios, while plastic coating bars are used for substrates prone to scratching.
