The TQC Sag and Levelling Film Applicator is a special film applicator with dual function. One side with 10 gaps from 75 to 300 micron to test the tendency to sag in relation to the film thickness. At the counter side 5 pairs of notches of increasing depth are made to create sets of two film stripes. The merging of the stripes can be evaluated to define the leveling ability. The high-grade stainless steel will not be affected by acid or base elements. Complies with ASTM D4400 and ASTM D2801.
