Coating Ink Blade Rod

Coating drawdown bars, with grooves of specific depths engraved on the surface of a metal rod, dispense a measured amount of coating or ink as they roll over the substrate, forming a uniform wet film. They are used in laboratories to simulate the coating process, test the leveling, hiding power, and other properties of coatings, and are suitable for coating preparation on materials such as paper and plastic films.
Selection
Select the scraper bar material based on the substrate surface roughness: use stainless steel bars for smooth surfaces and wrapped wire bars for rough surfaces. Match the groove depth to the coating thickness, with 25–100 μm specifications typically used for routine testing. Choose wide-groove types for high-viscosity liquids and narrow-groove types for low-viscosity liquids. Ensure compatibility between the scraper bar diameter and the Coater fixture.
