Film-winding Rod

The wire-wound coating bar forms grooves by winding wires of different diameters around the surface of a metal rod. During coating application, these grooves retain a specific amount of paint, which is then drawn across the substrate to create a uniform wet film. It is used in laboratory settings to simulate the blade coating process, enabling controlled film thickness for performance testing.
Selection
Select the corresponding wire diameter specification based on the target film thickness, taking into account the substrate flatness and paint viscosity. Stainless steel material is suitable for most solvent-based coatings. After use, promptly clean the wire gaps with the corresponding solvent to avoid solidification, which could affect coating accuracy.
