Overview
LENETA WC-46 Mayer Rods, also known as Wire-wound drawdown bar coating applicator or Mayer Rod, is a professional tool for preparing coatings into film thickness films. The model WC-46 has a 1.17mm wire diameter and can prepare wet-films approximately 89µm (3.5 mil) thick. Spreader width is 254mm (10 inches).
Features
Wide range of wire diameter: from 0.064mm to 1.9mm (2.5 to 75mils) to provide a variety of specifications to meet different film Film thickness requirements.
2. Accurate film film thickness: can be prepared from 4.5 µm to 150 µm (0.18 to 6 mils) film.
3. Reasonable design: Spreader width 254mm, suitable for most standard baseplates and cardboard; the total length of the rod body is 305mm, and there are 25mm hand-held parts at both ends, which is easy to operate; the rod diameter is 12.7mm, providing good rigidity.
4. Excellent material: made of all stainless steel, corrosion-resistant, non-rusting, suitable for water-based paints, and nonmagnetic design, can be used with steel plates on magnetic cards.
Principle
Mayer Rods controls Spreader Film thickness through precision wires (wires) wound on its surface. To use, an appropriate amount of paint is placed on one end of the substrate, and then the coating applicator is used to scrape the paint at constant speed and pressure. The wound wires create gaps in the paint, leaving a wet-film coating with uniform Film thickness and wire diameter on the substrate.
Applications
Coatings R & D and testing, inks performance evaluation, Adhesive Spreader, laboratory sample prepative, quality control, printing industry, New material coatings research
Standards
The data did not mention specific compliance criteria.
Steps
Select the bar type corresponding to the target wet film thickness (e.g. WC-46 corresponds to approximately 89 µm).
2. Pour the paint to be tested into a continuous line along one end of the substrate (e.g. test cardboard).
3. Hold the hand-held part at both ends of the bar, and place the winding end of the bar smoothly at the starting end of the paint.
4. With a uniform speed and appropriate pressure, scrape the bar straight across the entire paint area until the other end of the substrate.
5. Lift the bar, leaving a uniform wet-film coating on the substrate, which can be tested or observed after drying.
Notice
• Please select the appropriate bar type according to the required film Film thickness before use.
• Keep the bar perpendicular to the substrate surface during operation and scrape at a constant speed to ensure uniform film.
• After use, the bar should be thoroughly cleaned with a suitable solvent (if applicable) immediately to prevent the paint residue from drying up, affecting the accuracy of the next use and damaging the bar.
• Do not use hard objects to scratch or bend the bar, so as not to damage its precise winding structure.
Store in a drying environment to avoid bumping.
