resistance tester / for film / for coating
for film, for coating
The Elcometer 4270 Sag Tester is used to establish a coating’s resistance to sag due to gravity.
Made from stainless steel, the straight scraper has 10 notches of increasing clearance.
A contrast chart is immediately placed in a vertical position with the thinnest film at the top. The thickness at which the stripes join indicates the tendency to sag.
