Steel wire drawdown bar

The wire-wound drawdown bar consists of a metal rod wrapped with stainless steel wire, which creates a wet film of fixed thickness by controlling the gap between the wires. It is used in printing and coating testing to apply test films on substrates for evaluating properties such as color opacity, leveling, and other performance characteristics. It is suitable for comparing the uniformity of inks and coatings in laboratory settings and for testing the printability of paper.
Selection
When selecting, consider the wire diameter specification corresponding to the coating thickness requirement, typically ranging from 50 to 200 μm. Stainless steel material is resistant to solvent corrosion, and the uniformity of wire winding affects the consistency of the scraping application. Choose the corresponding length according to the testing standards and use it in conjunction with the base of the coating applicator. Narrow-width rods are used for small sample testing, while wide-width rods are suitable for standard sample preparation.
