Coating Application Rod

The coating rod is a metal rod that forms gaps by winding wires of different diameters, controlling the thickness of the coating retained during the spreading process. It is used in the laboratory to simulate roll coating and knife coating processes, preparing uniform wet films on surfaces such as paper and film. It is suitable for quality control applications such as ink opacity testing and coating adhesion evaluation.
Selection
Select the rod material based on substrate flatness, using hard stainless steel for rough surfaces. Match the wire diameter according to coating thickness requirements, typically within the 10–200 μm range. Choose models with larger gaps for high-viscosity fluids, and opt for shorter rods for quick-drying coatings. For ease of cleaning, prioritize rods with integral welding processes.
