Line Rod device

The wire-wound rod forms grooves by winding metal wires, and during coating, it scrapes the liquid to create a uniform wet film. It is used in the coatings and inks industry for preparing test coatings and controlling coating thickness and uniformity.
Selection
The selection of a wire-wound applicator should match the required wet film thickness, with the wire diameter specification chosen based on the sample's viscosity, and the rod length determined by considering the substrate width. Stainless steel is suitable for regular samples, while special coatings may require chrome-plated materials.
