Coating Film Spiral Rod

The wire-wound drawdown bar is a metal rod with grooves of specific depths engraved on its surface. During use, the coating material is placed on the substrate and spread evenly into a uniform wet film by scraping. The depth of the grooves determines the thickness of the coating film. It is used in laboratories to simulate the effects of processes such as spraying and roller coating, and to test the leveling, hiding power, and other properties of coatings.
Selection
When selecting, consider the substrate flatness and width matching the length of the wire-wound rod, with groove depth corresponding to the required coating thickness. Common specifications range from 25 to 500 μm. Stainless steel material resists solvent corrosion, and circular grooves are suitable for most fluids. Maintain a uniform speed during operation and clean promptly with the appropriate solvent after use.
