Overview
LENETA WC-16 Mayer Rods, also known as Wire-wound drawdown bar coating applicator or Mayer Rod, is a laboratory tool for preparing coatings into films of film thickness. The model WC-16 has a wire diameter of 0.41mm and can be used to prepare wet-film about 28µm thick. The Spreader width is 254mm, which is suitable for most standard size baseplates.
Features
Wide range of wire diameters: available in a variety of specifications from 0.064mm to 1.9mm (2.5 to 75mils).
2. Film Film thickness Coverage width: It can be prepared with a wet film thickness of 4.5 µm to 150 µm (0.18 to 6 mils).
3. Strong applicability: 254mm (10 inches) Spreader width is enough to meet most standard size baseplates and cardboard.
4. Reasonable design: the total length of the rod body is 305mm (12 inches), and there are 25mm hand-held parts at both ends for easy operation; the rod diameter is 12.7mm (1/2 inch), providing good rigidity.
5. Durable material: made of all stainless steel, corrosion-resistant, even in contact with water-based paints is not easy to rust, and is nonmagnetic, can be used with the steel plate on the magnetic card.
Principle
Mayer Rods' Working Principle is based on precision wire wound on its surface. When the operator places paint on the substrate and scrapes it with a coating applicator at uniform speed and pressure, the wound wire acts as a gap spacer to scrape off excess paint, leaving a wet-film coating on the substrate with a uniform film thickness in proportion to the wire diameter (wire diameter).
Applications
Coatings R & D and testing, inks performance evaluation, Adhesive Spreader, laboratory sample prepative, quality control and comparison
Standards
The data did not mention specific compliance criteria.
Steps
1. Select Mayer Rods of the appropriate diameter to match the target wet film thickness.
2. Pour or drop the paint sample to be tested on one end of the substrate (e.g. test cardboard or baseplate).
3. Handheld at both ends of the coating applicator, place the coating applicator perpendicular to the substrate in front of the coating.
4. At a uniform, stable speed and appropriate pressure, pull the coating applicator in the direction of the body to scrape it over the paint area.
5. Lift the coating applicator and check whether the wet-film formed on the substrate is uniform and free of stripes.
6. Carry out drying or curing according to the coating requirements, and then carry out follow-up testing or observation.
Notice
• Before use, select the appropriate bar type according to the desired wet film thickness.
• Maintain uniform speed and stable pressure during operation to ensure uniform film Film thickness.
• After use, the coating applicator should be thoroughly cleaned with a suitable solvent (if applicable) to prevent the coating residue from curing.
• When cleaning, pay attention to protect the wrapped wire to avoid collision or bending, which will cause the wire diameter to change.
Store in a drying environment to avoid contact with corrosive substances.
• This product is a precision tool and should not be used for Miscellaneous operations other than its intended purpose.
