Leneta Anti-Sag Meters
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 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.
