Overview
The US RDS No. 3 Mayer Rods are mainly used for preparing coatings of about 7 microns, suitable for Coatings, inks, and most fluid industries with precise film thickness (wet-film). The No. 3 Mayer Rods produced by RDS have a total of 4 models according to different diameters and processes, namely 6.35mm diameter molding coating rod and wire-wound coating rod, 9.4mm diameter wire-wound coating rod and 12.7mm diameter coating rod.
Features
1. Precise control of wet film thickness of about 7 microns
2. Made of stainless steel, strong durability
3. Wire-wound production process, wire diameter is only 0.08mm
4. Provide a variety of diameters and process models to choose from
5. The application width is 300mm, and the operation range is wide
Principle
Exact gaps are formed during the Spreader process by extremely fine steel wires (0.08mm diameter) wound around the rod body. As the coating rod moves on the substrate, excess fluid is scraped off, leaving a wet-film coating of exact thickness. The wet film thickness is mainly determined by the diameter of the wire. Coating Weight loss may vary.
Applications
Coatings, inks, fluid industry
Steps
1. Select the appropriate coating rod model
2. Place the coating rod on the substrate
3. Apply pressure evenly and move the coating rod smoothly
4. Clean and maintain in time after completing the Spreader
Notice
• The diameter of the steel wire of RDS No. 3 rod is only 0.08mm, which is equivalent to the thickness of the hair, and it is almost difficult to distinguish with the naked eye. It is recommended to use magnifying glass for observation
• Coating Weight loss may be different for coating rods with different diameters and processes although the wet film thickness is the same
• Avoid misoperation, improper cleaning and bumping during use to prevent wire breakage
• The probability of wire-wound coating rod breaking is about 2 thousand (NBchao statistics)
• Spreader substrate Hardness and personal use habits to choose the appropriate coating rod model
