Film Coating Bar

The film coating rod is a metal rod with grooves of specific diameters, used to create a uniform wet film on a substrate surface through a scraping method. By controlling the gap between the rod and the substrate, the thickness of the coating is regulated. It is employed in laboratories to simulate spraying and roller-coating processes, and to test properties such as the leveling ability and hiding power of coatings.
Selection
When selecting, consider matching the substrate roughness to the rod diameter, with common wire rod specifications corresponding to the wet film thickness. Choose between wound or blade-type structures based on the paint viscosity. For corrosive materials, opt for stainless steel or Teflon materials. Pay attention to the straightness and surface finish of the rod, and clean it promptly after use to prevent clogging.
