Paint Thickness Drawdown Bar

The paint thickness drawdown bar is a metal rod with grooves of varying depths, used to quickly determine the coating thickness during paint application by spreading the paint onto the substrate to form wet films of different thicknesses. The principle involves controlling the coating thickness through the groove depth, and after drying, measuring the film thickness to evaluate the paint's hiding power and usage. It is suitable for coating thickness testing of liquid paints, inks, and other coatings in both laboratory and field settings.
Selection
When selecting a drawdown bar, consider the substrate surface roughness; choose a model with deeper grooves for rough surfaces. Select based on the viscosity of the coating—higher viscosity coatings are suitable for bars with larger gaps. The test thickness range should cover the required coating thickness for the product. Choose a bar made of stainless steel for wear and corrosion resistance. The bar length should be greater than the width of the sample being tested. Clean promptly after use to avoid coating residue affecting accuracy.
