Bird-shaped coater

The bird-type applicator is a manual coating tool that uses its bird-beak-shaped blade to spread paint or ink onto a substrate, forming a uniform wet film. It controls the coating thickness through the gap between the blade and the substrate, and is used in laboratories to simulate the coating process, test coating properties, or adjust formulations. It is commonly employed in the research, development, and quality control of paints and inks.
Selection
When selecting a bird-type applicator, consider the substrate type and size, matching the width of the applicator. Choose the blade gap specification based on the desired wet film thickness. Pay attention to the corrosion resistance of the applicator material to suit the sample properties. During operation, maintain a uniform scraping speed to ensure an even coating.

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.

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.
