Overview
The RDS 3 #3/8 double wire-wound Applicator rod is a precision Spreader tool under the American RDS brand, which has more than 80 years of technical experience. This Applicator rod is designed with double wire-wound and is suitable for high viscosity Coating to reduce clogging and eliminate stitches. Its film accuracy can reach 0.1 micron, and the material is excellent. It enjoys a good reputation in the industry.
Features
1. Double wire-wound design is adopted, and the wide and shallow grooves are conducive to the flow of high viscosity coatings, reducing blockages and stitches.
2. Spreader uniformity with film accuracy up to 0.1 micron.
3. The material is stainless steel, which is sturdy and durable.
4. Provide a variety of specifications to choose from, and can accept customization.
Principle
The double wire-wound Applicator rod forms a wide and shallow groove by wrapping a smaller stainless steel wire around a larger tip. This structure facilitates the flow of high-viscosity coatings and reduces clogging. At the same time, the smaller tip wire creates a smaller discontinuity in the coatings flow, allowing the coatings to be more fully saturated, resulting in a precise, uniform film.
Applications
Experimental film, Coating research and development, quality control
Steps
1. Select the appropriate Applicator rod model according to the desired wet film thickness (e.g. 6.9 μm).
2. Applicator rod and substrate surface clean.
3. Coating an appropriate amount on one end of the substrate.
4. Hold both ends of the Applicator rod (50mm in hand width), pull the Applicator rod through the coating at a uniform speed and pressure, so that it forms a uniform wet-film over a 300mm application width.
Notice
• Applicator rod specifications (e.g. wet film thickness, application width) meet the experimental requirements before use.
• Maintain uniform drawing speed and pressure during operation to achieve ideal film effect.
• Applicator rod should be cleaned in time after use to prevent Coating from drying up and blocking the groove.
• Please keep it safe to avoid bumping and damaging the wire-wound structure.
