Wire-wound Drawdown Blade

The wire-wound drawdown bar consists of a metal rod wrapped with stainless steel wire, which forms a fixed wet film thickness by controlling the wire diameter and winding gap. In paint testing, it is drawn across the sample surface at a uniform speed to create an even wet film for evaluating properties such as leveling and hiding power. It is suitable for laboratory coating preparation and quality control.
Selection
Select the wire rod specification based on the viscosity of the coating to be tested; use a larger gap model for high viscosity. Consider the flatness of the substrate; choose a thicker wire diameter for rough surfaces. Match the wire rod number according to the wet film thickness required by the testing standard, commonly within the range of 10–200 μm. Clean promptly with solvent after use to avoid clogging of the wire gaps.
