Wire Wound Coating Applicator

The wire-wound drawdown bar is constructed from a metal rod wrapped with stainless steel wire, allowing the wet film thickness to be adjusted by controlling the gaps between the wires. When drawn evenly across a flat substrate, excess coating is scraped off, forming a uniform wet film. It is used in laboratories to simulate the coating process and evaluate properties such as leveling and hiding power of coatings.
Selection
Select the wire diameter specification based on the viscosity of the sample to be tested; low viscosity requires a small wire diameter. Consider the flatness of the substrate, using a larger wire diameter for rough surfaces. Verify that the nominal wet film thickness matches the experimental requirements. Stainless steel material is resistant to solvent corrosion, and the length of the wire-wound rod must cover the width of the sample. Clean and maintain promptly with the corresponding solvent after use.
