Line bar impression bed

The wire rod Coater transfers paint by rolling a metal rod on the substrate surface, forming a uniform wet film. It is used in laboratories to simulate the coating process and test the leveling and hiding power of paints. It is commonly employed for evaluating the coating quality of inks and paper.
Selection
Select the diameter of the wire-wound rod based on the roughness of the substrate; use a thicker rod for rough surfaces. Match the wire diameter to the viscosity of the coating, opting for a thicker rod for high viscosity. Choose the corresponding wire diameter specification according to the required coating thickness. Consider the corrosion resistance of the rod material.

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.
