Spiral Wire Coating Blade Rod

The wire-wound coating rod consists of a metal rod body wrapped with fine wires, controlling the amount of coating transfer through the gaps between the wires. Its function is to form a uniform wet film on the substrate surface, and it is used in the laboratory for coating and ink application. The principle is that during the coating process, excess fluid is blocked by the wires, allowing only a controlled amount of coating to pass through the gaps.
Selection
When selecting a wire-wound coating rod, it is necessary to consider the relationship between the wire diameter specification and the coating thickness, the corrosion resistance of stainless steel to solvents, and the impact of rod straightness on coating uniformity. The winding density of the wire should be matched according to the surface characteristics of the substrate, and an appropriate wire diameter range should be selected in combination with the viscosity of the coating to ensure a defect-free coating process without streaks.
