Using a sharp razor blade scalpel knife or other cutting device two cuts are made into the coating with a 30 45 degree angle between legs and down to the substrate which intersects to form an x.
The procedure consists of cutting a pattern of perpendicular lines through the adhesive all the way to the substrate then spreading pressure sensitive tape over the cuts and rapidly pulling it off.
The tqc cross cut adhesion test basic cutter is used to test the adhesion of dry coats of paint on their substrate by means of a series of cuts through the coating.
