Sample Coating Wire Rod

The drawdown rod is a metal bar used in the paint and ink industry to prepare uniform coating films, with grooves of specific depths engraved on its surface. Its principle involves scraping the coating evenly on a substrate, with the grooves controlling the wet film thickness to form test samples. Its purpose is to provide standard coatings for testing properties such as color, hiding power, and leveling. It is applied in laboratory quality control, product development, and formula comparison.
Selection
When selecting a drawdown rod, it is essential to consider that the groove depth range should match the thickness of the sample to be tested, typically ranging from 25 to 200 micrometers. The material should be stainless steel for corrosion resistance. The length should accommodate the width of common substrates. The groove precision must comply with standards such as ISO or ASTM. The handle design should ensure stable operation, and ease of cleaning and maintenance is important to extend the service life.
