Coating rods, otherwise known as Mayer Rods, are stainless steel wire wound rods that apply a precise, even layer of coating onto the substrate.
The No. 90 rod applies a heavy layer of coating needed for non-porous materials like metals, film, and glass.
The No. 28 rod applies a lighter layer of coating sufficient for papers.
Coating rods are manufactured to order and generally take several days to ship and several more days for delivery.
