Manual Film Applicator Rod

The manual coating rod evenly spreads the coating material on a substrate by moving a smooth metal rod at a constant speed, forming a uniform wet film. It is used in laboratories to simulate the coating process, measure coating thickness, and observe leveling properties. It is suitable for quality control in industries such as inks and coatings.
Selection
When selecting, consider the compatibility between substrate roughness and rod diameter, choose stainless steel for its resistance to solvent corrosion, and ensure the rod length covers the sample width. The operating environment determines whether to choose a model with scales or a smooth surface, and select rods with different gap specifications based on the viscosity range.
