Graduated flow coater

The graduated sag Coater controls the thickness of the coating through engraved grooves, and the fluid sag distance is observed when placed vertically. It is used to determine the sag resistance of coatings and is employed in the paint and ink industries for on-site construction viscosity control.
Selection
Select the corresponding groove depth specification based on the viscosity range of the tested material, consider matching the coating speed with the substrate type, ensure that ambient temperature and humidity meet standard testing conditions, choose stainless steel for laboratory use, and opt for a portable design for production sites.

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.
Sag resistance and leveling in constructability evaluation
This article primarily discusses how to balance the two key properties of sag resistance and leveling during the application of materials such as coatings and adhesives. Sag resistance refers to the material's ability to resist sagging due to gravity on vertical surfaces, while leveling refers to the material's ability to automatically smooth out its surface after application.

How to Coat High-Viscosity Slurry – Parameter Setting Tips for Blade Coaters
This article primarily discusses the parameter setting techniques for high-viscosity slurries on blade coaters. High-viscosity slurries exhibit characteristics such as shear thinning, so it is essential to leverage shear effects during coating to facilitate slurry spreading. After coating, the viscosity should recover quickly to prevent sagging.

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.
