Coating Extrusion Rod

The coating extrusion bar is a coating tool that forms a uniform wet film through the gap between the bar body and the substrate. The principle is that when the bar body rotates, it carries out the coating, and after scraping off the excess coating, a coating of the set thickness remains. It is used in the laboratory to simulate the coating process and test properties such as the leveling ability and hiding power of the coating.
Selection
When selecting, consider the substrate surface characteristics and paint viscosity. For rough surfaces, choose a bar with a larger diameter. High-viscosity paints are suitable for wire-wound bars, while low-viscosity paints are best used with blade bars. Match the bar number to the target coating thickness, and verify that the coating uniformity aligns with actual requirements.
