Overview
RDS 8 #3/8\ "Double wire-wound Applicator rod is a professional experimental Spreader tool with a wet film thickness of 18.3 microns. It is made of wear-resistant stainless steel, with a rod diameter of 9.52mm and an effective application width of 300mm. The product is developed and produced by RDS company in the United States with more than 80 years of technical experience. It is renowned in the industry for its film accuracy of up to 0.1 microns and excellent materials.
Features
1. Adopt double wire-wound design, suitable for higher viscosity Coating, can reduce clogging and eliminate stitches.
2. The wide and shallow groove structure is conducive to the flow of heavy coatings, and the smaller top line makes the coating more completely soaked.
3. Made of wear-resistant stainless steel, it is sturdy and durable.
4. The film accuracy is up to 0.1 micron to ensure the accuracy of the experimental results.
5. Provide a variety of specifications to choose from, and can accept customization.
Principle
The Applicator rod forms specific wide and shallow grooves by wrapping a smaller wire around the tip of a larger rod body. When scraped on the substrate, the grooves hold and transfer the Coating, precisely controlling the thickness of the wet-film to 18.3 microns. Its dual wire-wound design optimizes Coating flow, especially for high viscosity systems, effectively reducing clogging and ensuring film uniformity.
Applications
Suitable for a variety of industries that require precision film experiments, such as Coating R & D, inks testing, New material coating prepatives, etc
Steps
1. Place the Coating on the front end of the substrate to be Spreader.
2. Hold both ends of the Applicator rod and scrape the Applicator rod across the surface of the Coating and substrate at a stable and uniform speed and pressure.
3. Complete a single Spreader to form a wet-film of the specified thickness.
Notice
• Applicator rod clean, drying and no residue in the groove before use.
• Keep the force and speed uniform when scraping to obtain a flat film.
• After use, it should be thoroughly cleaned with a suitable solvent in time to maintain accuracy and prolong service life.
• Please select the appropriate Applicator rod model according to the Coating viscosity. The double wire-wound design is more suitable for high viscosity Coatings.
• Keep it properly when storing to avoid bumping and damaging the precision wire-wound structure.
