Micron Coating Applicator

The micro applicator controls the transfer amount of coating through precisely machined grooves or gaps, uniformly applying liquid samples onto the substrate surface to form a specified thickness of wet film. It is used in laboratories to simulate the blade coating process, testing properties such as the hiding power and leveling of coatings, and is employed in industries such as inks and paper for quality control.
Selection
When selecting, consider matching the substrate type with the Coater material, determine the groove shape based on the sample viscosity, and choose the coating width according to the testing standard requirements. The wet film thickness range should cover common coating amounts, while ease of operation affects the efficiency of repeated testing. Environmental adaptability involves corrosion resistance requirements.

Laboratory rod coater for submicron wet film preparation of photoresist.
This article introduces the process of using a laboratory bar coater to prepare submicron wet films of photoresist.
Selection of laboratory grinders is based on the fineness requirements of coatings, choosing between ball mills or sand mills.
The selection of a laboratory grinder should be based on the fineness requirements of the coating. A fineness greater than 50 microns indicates coarse dispersion, 10 to 50 microns is considered medium fineness, and less than 10 microns requires high fineness dispersion.
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 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.
