Adhesion coater

The adhesion Coater forms a wet film of uniform thickness on the substrate surface through mechanical scraping, simulating the actual application state of the coating. Its purpose is to prepare standard specimens for adhesion testing, ensuring the accuracy of evaluating the bonding strength between the coating and the substrate. It is applied in the quality control processes of the paint and ink industries.
Selection
When selecting, consider the substrate flatness to match the precision of the Coater gap, as the coating viscosity determines the wear resistance of the blade material. The test standards correspond to the coating width specifications. The influence of ambient temperature and humidity requires the inclusion of adjustment functions, while ease of operation focuses on the design for 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.
