Coating Drawdown Rod

The paint drawdown bar is a surface treatment tool that applies paint onto a substrate using a metal rod engraved with grooves, creating a uniform wet film. The depth of the grooves determines the coating thickness, and it is used for quickly evaluating the leveling, hiding power, and color effects of paints. Commonly used in laboratories and production lines, it assists in adjusting formulations and inspecting application quality.
Selection
When selecting a drawdown bar, consider the coating type and testing requirements. Use a deep-groove bar for high-viscosity coatings and a shallow-groove bar for low-viscosity ones. Match the groove specifications to the target film thickness, and ensure durability with a metal construction. Verify standards such as ASTM or ISO to guarantee testing consistency. Using multiple specifications in combination allows for comparison of different thickness effects.
