Used in ASTM D4400, Test Method for Sag Resistance of Paints

This is a drawdown blade with a series of notches of successively higher clearance. 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 development of this instrument and its versatility for control and research have been described in published reports. Official Digest (JCT), October 1962. Official Digest (JCT), January 1964. 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.
