Wire-wound Ink Applicator Bar

The wire-wound drawdown bar is composed of a metal rod wrapped with stainless steel wires, forming a wet film of fixed thickness by controlling the gap between the wires. The coating material is placed on the substrate and drawn down with uniform pressure and speed, with the gap between the wires determining the coating thickness. It is used for opacity testing of inks and coatings, as well as for proofing in the printing industry to ensure color consistency.
Selection
Select the wire diameter specification based on the viscosity of the material to be tested; use a larger wire diameter for high viscosity. Consider the flatness of the substrate—choose a wound-type applicator for rough surfaces. The coating thickness should match the gap of the steel wire, typically ranging from 10–200 μm. Experimental ambient temperature affects viscosity and should be adjusted accordingly. Verify that the coating is uniform and free of discontinuities after application.
