Description
Wire-wound rods are precision tools used to apply coatings with controlled thickness onto substrates such as glass, wood, or black/white test charts. Both the rod and the wire are made of stainless steel, providing corrosion resistance and long-term durability. By drawing down a coating with a known wire-wound rod, uniform thin films are created, making them ideal for quality control, laboratory testing, and coating research. These rods can be used manually by gripping both edges or with a holder for consistent application.
These applicators are particularly suitable for very thin films on flexible or delicate materials such as paper, cardboard, leather, textiles, and foils. Each rod has the maximum wet film thickness engraved on its end for easy reference, and several samples can be drawn down side by side simultaneously. The rods have an effective wire-wounding length of 200 mm, total length of 240 mm, and are available in a wide range of theoretical wet film thicknesses from 6 µm up to 200 µm, with a standard bar diameter of 10 mm, making them versatile for diverse coating applications.
