Blade Coating Wire Rod

A wire-wound drawdown bar is a metal rod wound with steel wire of a specific diameter, used to create a uniform wet film of coating on a substrate by drawing it across the surface. The gap formed by the wire controls the coating thickness, making it suitable for simulating coating processes and quality control in laboratory settings.
Selection
Select the wire-wound applicator number based on the target wet film thickness, with each number corresponding to a specific coating thickness. Consider the viscosity of the paint and the smoothness of the substrate; for high viscosity, choose an applicator with a larger gap. The diameter of the applicator affects operational stability, with a 50mm width commonly used. Clean immediately with solvent after use to prevent clogging.
