Stainless steel scraper Rod

A stainless steel drawdown rod is a smooth-surfaced metal rod used for spreading liquid materials such as coatings and inks onto substrates to form a uniform wet film. Its principle relies on the gap between the rod and the substrate to control the coating thickness, making it suitable for laboratory tests of coating hiding power, color difference, or drying performance.
Selection
When selecting, consider the rod diameter corresponding to the coating thickness, with common specifications ranging from 25μm to 200μm; choose 304 stainless steel for corrosion resistance; ensure the length matches the substrate width; the surface must be free of scratches to avoid affecting the scraping effect; and determine the type (grooved or smooth) based on the testing standards.
