Coating Applicator

The Coater evenly applies the coating onto the substrate surface using a blade or roller, forming a wet film of specific thickness. It is used in laboratories to simulate coating processes, test properties such as leveling and hiding power of coatings, and is suitable for coating preparation and quality control of materials like paper and plastic films.
Selection
When selecting a Coater, consider the type and size of the substrate to match the coating width. Choose a blade or roller with an appropriate gap based on the required coating thickness. Determine the coating speed in combination with the viscosity of the coating material. Prioritize corrosion-resistant materials to accommodate different solvent-based coatings. Verify that coating uniformity meets the testing requirements.

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.
