Spiral Wire Film Applicator Rod

Wire-wound coating rods control the transfer of coating material through metal wires wound around the rod body. The principle is that as the rod rolls, the gaps between the wires retain a specific amount of coating material, forming a uniform wet film. Their function is to simulate the blade coating process in laboratory settings, and they are used for testing coating thickness and evaluating ink adhesion on substrates such as paper and plastic films.
Selection
When selecting a wire-wound coating rod, match the rod length to the substrate width. Choose the wire diameter based on the desired wet film thickness. Consider the paint viscosity to select a model with the appropriate winding density. Verify the chemical compatibility between the rod material and the coating. Ensure the rod’s straightness error is less than 0.1mm to guarantee coating uniformity.
