Color scraping wire Rod

The drawdown bar is a metal rod with spiral grooves that quantitatively transfers paint or ink onto a substrate through the grooves to form a uniform wet film. It is used in laboratories to simulate printing and coating processes and to test properties such as color and hiding power.
Selection
The selection of a coating applicator rod should match the substrate thickness and testing requirements: coarse grooves are suitable for thick coatings, while fine grooves are for thin coatings. Consider the viscosity of the coating—choose deep grooves for high viscosity. Verify the theoretical wet film thickness corresponding to the rod number. Ensure the rod is straight, with a smooth surface and no defects.
