Stainless steel Rod for scraping

The drawdown stainless steel rod is a cylindrical tool with a graduated scale on its surface, designed to achieve uniform coating by controlling the coating thickness. During use, the coating material is applied to the substrate, and the steel rod is drawn with a fixed pressure to form a wet film. It is commonly used for ink opacity testing, coating comparison experiments, and printability assessments.
Selection
When selecting, consider the substrate roughness to determine the steel bar diameter, choose the wire-wound or doctor blade model based on the coating thickness range, select stainless steel or electroplated material according to the coating viscosity, decide between ordinary or rust-proof treatment based on the experimental environment, and match the manual or mechanical fixation method to the application scenario.
