What Are The Usage Scenarios for Mayer Rods?
Publish Time: 2025-10-21 Origin: Site
The Mayer Rod, a precision coating tool, achieves controlled thickness through wire winding or groove processing. Available in two configurations wire-wound and formed—it is primarily used for laboratory R&D and small-scale coating applications in manufacturing lines. The coating thickness is determined by the winding diameter, with broad material viscosity compatibility. This essential tool serves as a cornerstone in industries such as printing, coatings, and electronics.
I. Core application scenarios
Meyer rods are widely used in areas where coatings need to be prepared with precision, repeatability and small batches.
There are several usage scenarios:
Printing and packaging industry: ink sampling, plastic film/aluminum foil protective layer/barrier coating, ensure that packaging oxygen and water resistance meet the standards.
Coating and ink industry: prepare standard coating during new product research and development, test gloss and covering power; small batch coating of metal plate, wood plate and other base materials on the production line to reduce the cost instead of large equipment.
Electronic and new energy industry: coating of conductive paste for flexible circuit board and coating of photovoltaic backplane insulation glue; in the laboratory research and development of lithium battery, coating of positive and negative electrode paste on copper foil and aluminum foil, and controlling the thickness consistency to ensure the accuracy of battery performance test.
Cosmetics and pharmaceutical industry: control of film thickness of cosmetics, creams and emulsions; uniform coating of ointments and gels to ensure consistent distribution of medicinal ingredients.
Research and laboratory: sample preparation of polymer materials and nano-coating for mechanical properties, light transmittance, corrosion resistance and other tests, and rapid comparison of different formula effects.
II. Wire diameter and coating thickness correspondence table
The wet film thickness of the wire-shaped Meyer rod can be estimated by the wire diameter, and the molding type can be matched with the same thickness according to the groove specification. The following is the corresponding relationship between common parameters:
Wire diameter (mm) | thickness of wet film （μm） | Applicable material viscosity | Typical application scenarios |
0.06-0.11 | 6-12 | Low viscosity (e.g., dilute ink, conductive paste) | Electron component conductive layer, film printing sample |
0.14-0.28 | 15-30 | Medium and low viscosity (such as water-based coatings, emulsions) | Cosmetic cream application, paper coating test |
0.37-0.56 | 40-60 | Medium viscosity (e.g., oil-based coatings, adhesives) | Lithium battery plate research and development, wood board paint sample |
0.65-0.93 | 70-100 | Medium and high viscosity (such as thick paste type coating, ink) | Metal plate protective coating, packaging barrier layer coating |
1.22-1.86 | 120-200 | High viscosity (e.g. wax, hot melt glue) | Floor polishing agent coating, thick film material sample preparation |
III. Selection Notes
Material selection: all 304 stainless steel, corrosion resistant and easy to clean, avoid paint residue and cross contamination.
Limitations: High viscosity materials are recommended to be paired with rotary scraper; when the coating thickness exceeds 200μm, special Twin/Gapped double filament Meyer rod should be selected.
Base material adaptation: flexible base material should control the coating pressure to avoid deformation of the base material; rigid base material can be operated normally to ensure uniform thickness.
