Wire-wound Drawdown Bar

The wire rod Coater for paint film forms a uniform wet film by rolling a metal rod wound with stainless steel wire on the substrate surface, where the grooves between the wires carry a precise amount of coating. It is used in laboratories to simulate the blade coating process, controlling the paint film thickness for quality inspection.
Selection
When selecting, consider matching the wire diameter specification to the substrate type and coating viscosity. The wire material must be corrosion-resistant, the rod length should cover the sample width, the handle design should ensure stable operation, and the coating thickness range must meet the requirements of testing standards.
