Overview
The RDS#23 wire-wound drawdown bar is a spiral wire coating tool, model 23# 3/8", specifically designed for high-quality, quantitative application of coatings or color pastes onto substrates to achieve a specific wet film thickness. This drawdown bar can achieve a wet film thickness of up to 52.6 μm, with an effective coating width of 30 cm. It features 5 cm handle sections at both ends for convenient operation, making it suitable for preparing larger wet film thicknesses in the industry.
Features
1. Capable of preparing wet films with a large thickness range, covering 4.6μm to 217.2μm, with this model at 52.6μm.
2. The effective coating width reaches 30cm, meeting the general needs of users.
3. Both ends feature a 5cm-long handle section, designed for user-friendliness and ease of operation.
4. Utilizes a wire-wound production process to ensure uniform and quantitative coating.
5. Made of stainless steel, durable and easy to clean.
Principle
The RDS#23 wire bar Coater utilizes a wire-wound design, where the gaps formed by the stainless steel wires evenly spread the coating or color paste onto the substrate surface during the coating process. This allows for precise control of the wet film thickness to 52.6μm, achieving high-quality and quantitative coating results.
Applications
Coating application, pigment paste application, wet film thickness preparation
Standards
Industry Standard
Steps
1. Prepare the substrate and the coating or color paste.
2. Place the applicator at the starting position on the substrate.
3. Apply even pressure and draw the coating in a straight line.
4. After completing the application, clean the applicator for the next use.
Notice
• Ensure the Coater and substrate surfaces are clean before use.
• Maintain uniform speed and pressure during coating to avoid uneven thickness.
• Clean the Coater promptly after use to prevent residue buildup.
• Store in a dry environment and avoid impacts to prevent damage to the wire-wound structure.
