Laboratory Wire Rod Applicator

The lab wire-wound rod Coater forms a wet film of specific thickness on the substrate surface by rolling a metal rod wound with stainless steel wire. It is used to simulate the coating process in the laboratory and test the leveling and hiding power of paints and inks. It is suitable for testing the coating uniformity of materials such as paper and plastic films.
Selection
Select the corresponding wire-wound coating rod based on the desired wet film thickness, taking into account the substrate flatness and sample viscosity. The wire diameter specification determines the coating thickness: rough substrates require thicker wire diameters, and high-viscosity materials are suitable for models with larger winding spacing. After use, clean thoroughly with solvent to avoid residue.

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.
Coating film preparation techniques: comparison between wire-wound applicators and wet film preparators
This article compares two commonly used tools in laboratory coating film preparation: the wire rod coater and the wet film applicator.
Application of Wire Bar Coater in the Preparation of Coating, Ink, and Printing Samples
A wire-wound rod coater is a laboratory tool used for preparing uniform wet film coatings on flat substrates, widely applied in the production of samples in the coatings, inks, and printing industries.
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.
