Multi-slot coater

The multi-slot applicator simultaneously spreads different thicknesses or types of coating samples through multiple independent slots, forming parallel coating strips on the substrate. It is used for rapid laboratory comparison of coating leveling, hiding power, or drying effects. It is suitable for formulation screening and quality control of inks, paper, and plastic films.
Selection
When selecting, consider the matching between substrate thickness and the applicator gap, the corrosion resistance of stainless steel material, determine the number of slots based on comparative experiment requirements, note that slot width affects sample consumption, and ensure the operating environment maintains a level surface to avoid uneven coating thickness.

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.
