Bar Coating Applicator

The rod Coater forms a uniform wet film by rolling a metal rod wound with stainless steel wire on the substrate surface. It is used in laboratories to simulate the blade coating process and test the coating effects and thickness control of paints and inks.
Selection
When selecting, consider the wire diameter to determine the coating thickness, match the substrate material to the application requirements, ensure the operating length fits the sample size, maintain uniform wire winding to affect coating quality, and design the handle for ease of use.

Application of Two-Step Method with Pre-Coating and Fine-Coating in Eliminating Bubble Defects for Dual-Blade Coater
The dual-blade coater employs a two-step method of pre-coating and precision coating to eliminate bubble defects during the coating process. In the pre-coating stage, high shear force is applied to break the bubbles in the slurry, causing them to rupture and rise to the surface. The precision coating stage then precisely controls the coating thickness, removing any remaining bubbles to form a uniform wet film.
Key Points for Controlling Coating Longitudinal Uniformity with Manual Rod Coater Constant Speed Dragging Techniques
This article discusses how to control the longitudinal uniformity of the coating by dragging at a constant speed when using a manual wire rod coater. A constant-speed drag is crucial, as it directly determines the consistency of the wet film thickness.
Derivation and Validation of the Quantitative Relationship between Wire Diameter and Wet Film Thickness in Wire Wound Coating Bars
This paper investigates the relationship between the wire diameter in a wire-wound rod coater and the wet film thickness. Theoretically, under ideal conditions, the wet film thickness is approximately half of the wire diameter.
Actual Coating Thickness Deviation of Stainless Steel Wire Rod Coaters at Different Slurry Solid Contents
This article analyzes the actual coating thickness deviation of stainless steel wire rod coaters under different slurry solid contents. The study finds that the solid content of the slurry affects its viscosity and flowability, leading to deviations in the actual coating thickness from the theoretical value.

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.
