Thin Film Rod Coater

The wire-wound rod Coater forms a wet film of specific thickness on the substrate surface by rolling a metal rod wound with stainless steel wire. The gap between the wires determines the coating thickness, and it is used in laboratories to simulate the blade coating process, test coating uniformity, and evaluate ink hiding power.
Selection
When selecting, consider the substrate type and viscosity; choose a thicker wire specification for high-viscosity materials. Match the wire diameter based on the coating thickness requirement, as larger diameters result in thicker coatings. Pay attention to the corrosion resistance of the rod material, and maintain a uniform translation speed during operation to avoid uneven thickness.
