Coatings applied on non-horizontal surfaces will sag due to gravity. Sag resistance is a factor of the composition and viscosity of the coating, as well as the applied thickness.
The applicator is a U-shaped drawdown bar with a series of 1/4 inch (6.4 mm) wide notches of varying clearances, spaced 1/16 inch (1.6 mm) apart. It is 5 inches (127 mm) wide and produces a total film width of 3-3/8 inches (86 mm).
When a drawdown is made, a series of parallel stripes of different wet film thickness will be formed. This panel is placed on a vertical surface with the stripes horizontal and the thickest stripe lowest. As the film stripes sag downward, some of the uncoated 1/16 inch (1.6 mm) spaces may become entirely covered. The clearance of the gap that produces the thickest film stripe, not sagging completely to the stripe below, is the anti-sag index of the coating.
The Anti-Sag meter allows quantification of the sagging properties of coatings.

Stainless Steel Bar Film Applicators
These 440 grade Stainless Steel Bar Film Applicators are the highest quality and easiest to clean and maintain due to their simple design and rugged construction. The theoretical wet film thickness is etched onto every drawdown bar. The theoretical wet film thickness is roughly one-half the actual gap clearance.
If you have a gap clearance of 6 mils, the theoretical wet film thickness etched on the bar applicator is 3 mils. We cannot guarantee that you will draw-down the theoretical wet film thickness. The drawdown process consists of many variables.
The actual wet film thickness can vary from 50% to 90% of the gap depending on the gap clearance.
• Every drawdown bar is certified in the lab and comes with a NIST traceable calibration certificate.
• Packaged in a handy reusable storage box to help prevent damage.
• Made of 440-grade stainless steel, ground to tight tolerances for repeated use.
