Wire-wound Wet Film Applicator Bar

The wire-wound wet film applicator consists of a metal rod wound with stainless steel wires, which forms a wet film on the substrate through scraping. The wet film thickness is determined by the diameter of the steel wires. It is used for the coating preparation of paints and inks, facilitating subsequent testing of coating uniformity or hiding power.
Selection
When selecting, consider the required wet film thickness corresponding to the wire-wound rod specification. The flatness of the substrate influences the choice of rod length, and thick wire-wound rods are suitable for viscous fluids. Stainless steel material provides corrosion resistance. After use, promptly clean the gaps between the wires with solvent to prevent clogging.

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.
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 working principle of laboratory wire rod coaters and methods for controlling coating thickness
The laboratory wire rod coater is a precision instrument used to prepare uniform, thickness-controllable wet film coatings on substrate surfaces. Its core components include a coating rod, a flat coating platform, clamps for securing the substrate, and a mechanical system that drives the coating rod to move at a constant speed.
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.
