Miniature Lab Coater

A small laboratory Coater evenly applies coatings onto a substrate surface using a blade or roller, simulating the coating process in industrial production. Its principle involves controlling the wet film thickness through mechanical pressure, making it suitable for laboratory research, development, and quality control. It is commonly used in surface treatment tests for materials such as paper and films.
Selection
When selecting, it is necessary to match the substrate dimensions and coating width, consider the coating speed and thickness adjustment range. Pay attention to the material and flatness of the doctor blade to ensure coating uniformity. Choose a roller or blade-type structure based on the viscosity of the coating, while also considering the convenience of equipment cleaning and maintenance.

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.
