Surface Coating Rod

The coating rod controls the transfer amount of the coating through the grooves on its metal surface, forming a uniform wet film on the substrate. It is used in laboratories to simulate the blade coating process and test the leveling, hiding power, and other properties of coatings. It is suitable for quality control in industries such as inks and paper.
Selection
When selecting, consider matching the substrate roughness to the groove depth, as the viscosity of the coating determines the wire diameter specification, and experimental accuracy requirements influence the rod material. Stainless steel rods are solvent-resistant, while carbon steel rods are cost-effective. The shape of the groove affects the coating performance, with spiral grooves being suitable for high-viscosity materials.
