Printing Application Rod

The coating rod for printing is a metal rod with specific engraved scales on its surface, which forms a uniform wet film on the substrate through a scraping method. The depth of the engraved grooves controls the thickness of the coating, making it suitable for laboratory simulation of coating processes such as ink opacity testing and paper coating preparation.
Selection
Select the rod material based on the substrate roughness; use stainless steel rods for smooth surfaces. Match the groove depth to the coating thickness; choose low-number rods for thin coatings. Consider the paint viscosity; select rods with wider groove spacing for high-viscosity paints. After use, thoroughly clean with solvent to avoid residue.
