Micron Coating Rod

The micrometer coating applicator rod forms a uniform wet film on the substrate by retaining a specific amount of coating material through grooves of precise depths engraved on the surface of a stainless steel rod during the scraping process. It is used in laboratories to simulate spraying and roller coating techniques, allowing for controlled coating thickness in quality inspections and formulation adjustments.
Selection
When selecting, consider the compatibility between substrate flatness and bar hardness. The groove depth corresponds to the required wet film thickness, and the width should accommodate the sample size. Stainless steel material is resistant to solvent corrosion. Maintain a uniform speed during operation. Choose the appropriate gap based on viscosity; use a deeper groove bar for high viscosity.

Effect of Different Coating Speeds on Film Thickness Consistency in an Adjustable Film Applicator
This paper studies the influence of coating speed of an adjustable film applicator on film thickness uniformity. In the experiment, the coating blade gap was fixed at 100 μm, and a resin solution with a viscosity of 200 mPa·s was used to prepare films at five speeds ranging from 10 to 80 mm/s, followed by thickness measurements.
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.
Scraper Fineness Gauge for Determining the Fineness of Paste Inks
The Scraper Fineness Gauge is used to measure the dispersion degree of pigment particles in products such as paste inks. Its principle involves scraping a film on a scraper plate with wedge-shaped grooves and observing the scale at which particles appear to assess the fineness, with the result expressed in micrometers.
The role of the coating machine in the preparation of fuel cell membrane electrode assemblies
The film coating machine is a key equipment for preparing the membrane electrode, the core component of fuel cells. It evenly coats a catalyst-containing slurry onto a substrate using techniques such as blade coating, slot-die extrusion, or spraying, forming a catalytic layer ranging from a few micrometers to several tens of micrometers in thickness.
The difference between a wire-wound rod coater and an extrusion coating rod
This article primarily compares the technical differences between wire-wound and extrusion coating rods. Although they are interchangeable in most scenarios, there are subtle variations in liquid loading capacity due to their distinct groove principles.
