Wet Film Wire Rod Applicator

The wet film wire-wound rod Coater rolls on the substrate surface using a metal rod wrapped with stainless steel wire, where the gaps between the wires form a wet film coating of a fixed thickness. It is used in laboratories to simulate the blade coating process, preparing uniform test coatings on materials such as paper and film.
Selection
When selecting, consider the substrate type and viscosity; use a larger wire diameter for high-viscosity materials. Check the rod number comparison table based on the desired wet film thickness. Verify the straightness of the rod body and the uniformity of the wire winding. Stainless steel is suitable for most coatings, while electroplated models are recommended for highly corrosive materials.

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.

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.
