Adjustable Film Coating Bar

The film coating rod evenly spreads liquid on the substrate surface using a smooth metal rod to form a wet film of a set thickness. It is used for the coating preparation of paints and inks, facilitating subsequent tests for properties such as hiding power and color difference.
Selection
Select the rod diameter corresponding to the wet film thickness according to the test standard; choose the grooved or smooth rod type based on the sample viscosity; consider the substrate flatness to opt for manual or electric drawdown rods; and use corrosion-resistant materials to accommodate samples with different chemical properties.
