Paint Coating Application Rod

The coating rod is a coating tool with grooves of specific depths engraved on the surface of a metal rod. By pouring the coating into the grooves and scraping it evenly across the substrate surface, a wet film of uniform thickness is formed. It is used in laboratories to simulate processes such as spraying and roller coating, and to test the leveling and hiding power properties of coatings.
Selection
Select the groove shape based on the viscosity of the coating to be tested: use a rectangular groove for high viscosity and a wedge-shaped groove for medium to low viscosity. Determine the wet film thickness according to the testing standard, and select the corresponding groove depth specification. The flatness of the substrate influences the choice of rod material: use a stainless steel rod for glass plates and a round rod for soft substrates. Maintain uniform pushing force during operation.
