Mayer Bar Applicators for Simple, Reproducible Thin Films
Wire-wound or formed bars for coating thicknesses from 6 µm to 200 µm
Overview | Specifications | Features | Gallery
Produce quick, simple, and consistent coatings with Ossila Mayer Rods. Choose between wire-wound or formed, each available in a wide range of coating thicknessess depending on your coating needs. All of our Mayer rods are made from corrosion resistant stainless steel making them suitable for a variety of coating solutions.
Wire-wound Mayer rods consist of a central metal rod with a wire of a specific diameter wound around it. Formed Mayer rods have a groove machined into the rod that mimics the gap that is present between the wires in a wire-wound rod. In both cases, the gaps formed between the applicator and the substrate determine the coating thickness

Wire Diameter for Wire-Wound Rods
For most wire-wound Mayer bars the wire is closely packed so that, ideally, there are no gaps between the wires. In this situation the wet-film thickness can be easily approximated and is given by the diameter multiplied by a geometric factor of 0.10731, the below table gives the upper wet-film thickness for each diameter of wire.
| Wire Diameter | Wet Film Thickness |
|---|---|
| 0.06 mm | 6 µm |
| 8 µm | |
| 0.10 mm | 10 µm |
| 0.11 mm | 12 µm |
| 0.14 mm | 15 µm |
| 0.19 mm | 20 µm |
| 0.24 mm | 25 µm |
| 0.28 mm | 30 µm |
| 0.37 mm | 40 µm |
| 0.47 mm | 50 µm |
| 0.56 mm | 60 µm |
| 0.65 mm | 70 µm |
| 0.75 mm | 80 µm |
| 0.93 mm | 100 µm |
| 1.22 mm | 120 µm |
| 1.40 mm | 150 µm |
| 1.86 mm | 200 µm |
Formed rods do not have conversion tables for wire diameter to wet film thickness, instead the shape of the groove and the width of the crest between grooves is controlled to provide the targeted wet film thickness. The standard thicknesses that are made with formed rods follow those available for wire-wound rods so you can easily adapt coating processes to these new types of rod.
Mayer Rod Features
Formed or Wire-Wound
Choose between traditional wire-wound or new formed Mayer rods to fit your coating needs. Both achieve highly reproducible films, but formed rods are less prone to damage and contamination with an easily controlled packing density of the grooves.
Manual or Automatic Coating
Ossila Mayer Rods are built for both manual and automatic coating techniques. Manual coating processes are simple and budget-friendly, or you can remove the risk of human error by using your Mayer rods with the Ossila Automatic Film Applicator.
Custom End Machining
As standard all each Mayer rod comes with M4 tapped ends. This provides maximum adaptability of the bar across multiple applicators. For more specific requirements, we can provide you with custom end machining—just contact us to discuss your requirements.
Save on Mayer Rod Sets
Our full Mayer rod sets give you complete flexibility in your coating processes. Ideal for comprehensive coating research, you can save with the set compared to buying each Mayer rod individually. We offer sets that are both wire-bound or formed, each including all available coating thicknesses.
