Overview
The American RDS 5 Wire-Wound Coating Rod (Model: 5# 3/8) is a professional tool for preparing precise film layers in the laboratory, manufactured from high-grade stainless steel. This product is a wire-wound coating rod with a diameter of 3/8 inch (9.5 mm), a total length of 400 mm, a coating width of 300 mm, a gripping width of 50+50 mm, and is capable of producing a wet film thickness of 11.4 μm.
Features
1. Made of high-grade stainless steel for enhanced durability.
2. Wire-wound design provides precise wet film thickness control.
3. Available in multiple diameter options (1/4, 3/8, and 1/2 inches).
4. Total length of 400mm with a coating width of 300mm, ideal for laboratory use.
5. Wire diameter of 0.13mm ensures coating accuracy.
Principle
The wire-wound applicator creates grooves by winding precision steel wires around a stainless steel rod. When the applicator is drawn across a substrate surface, the coating material in the grooves is uniformly transferred onto the substrate, forming a wet film coating of a specific thickness. Although rods of different diameters can produce wet films of the same thickness, the actual coating amount may vary due to differences in groove shape and the diameter of the main rod.
Applications
Membrane layer preparation in the laboratory, coating testing, and coating research
Steps
1. Evenly pour the coating onto one end of the substrate.
2. Hold both ends of the coating rod and scrape it across the substrate surface at a constant speed and pressure.
3. Ensure the coating rod remains parallel to the substrate surface.
4. After coating is complete, clean the coating rod and store it properly.
Notice
• Ensure the coating rod is clean and free from contamination before use.
• Maintain constant speed and pressure during the coating process.
• The coating amount may vary depending on the diameter of the coating rod.
• Clean promptly after use to avoid residue buildup.
• Store carefully to prevent collisions and avoid deformation of the steel wire.
