  • Two Anti-Sag Meters available

    • ASM-3 high range

    • ASM-4 medium range

  • The notch clearance is related to the degree of sagging and provides a numerical value referred to as the Anti-Sag Index.

  • The higher the Anti-Sag Index the better the sag resistance of the coating.

  • The Anti-Sag Meter is called for in ASTM Method D 4400 and Federal U.S. Fed, No. 141 Method 4494 test methods and is essential equipment in paint laboratories in the U.S.A. and throughout the world.

    1 Mils are exact, microns are approximate. Wet film thickness is about half of the clearance.


  1. Preparation of Coating, stir thoroughly and adjust to 23°C (73.5°). Pre-shear in accordance with one of the methods furnished and test immediately thereafter.
  2. Attach the straight-edge onto the drawdown plate in suitable position.
  3. Place a test chart on the drawdown plate under the clip.
  4. Place Anti-Sag Meter on the chart, with it's open side toward operator and it's shoulder against the straight edge.
  5. Position Catch-Paper
  6. Place a suitable quantity (8-10mL) of pre-sheared paint directly in front of the blade and draw down uniformly at about 6" (150mm) per second.
  7. Promptly fasten the drawdown chart to a vertical surface, with stripes horizontal and left edge (thinnest stripe) at the top, and allow to dry in that position.
  8. Rate the Drawdown.
  9. Note the notch numbers marked on the Anti-Sag Meter and Identify the corresponding stripes accordingly.
  10. Ignore the leading and trailing edges, and observe only the central 5-1/2" (140 mm) of blade path corresponding to the black area of Form 7B.
  11. The lowest (thickest) stripe that does not touch the one below itself is referred to as the index stripe, and its notch number is the Anti-Sag Index of the paint.
  12. For more precise Anti-Sag Index, add to the Index stripe number the product of the post-index clearance step and a fractional degree to which it has failed to merge with the next lower stripe.
