Wire Wound Coater

The wire-wound rod Coater transfers coating by rolling a metal rod wrapped with steel wire on the substrate surface, with the wire gaps controlling the wet film thickness. It is used in laboratories to prepare uniform coating samples and is paired with thickness gauges for basic performance tests such as coating hiding power and leveling.
Selection
Select the wire diameter specification based on the viscosity of the paint; use a thicker wire diameter for high viscosity. Determine the length of the rod according to the width of the substrate, with 30cm being common. Stainless steel material resists solvent corrosion, and it should be promptly cleaned with the corresponding solvent after use. Note that the wire rod number corresponds to the theoretical coating amount; for example, a No. 10 rod corresponds to a wet film thickness of 10μm.

The difference between a wire bar coater and a gap-type wet film applicator.
The wire-wound drawdown bar directly quantifies the coating through the gap between wires, making it suitable for thin coating preparation with high precision, particularly for low-viscosity fluids. In contrast, the gap-type wet film applicator indirectly controls film thickness through the groove depth, with the actual coating thickness significantly influenced by material properties, making it more suitable for high-viscosity coatings and thick film preparation.
