Key feature : To check the bent resistance of coating at 3 mm. This ensures durability of film under mechanical stress.
Key feature : The cross cut test, also described as cross-hatch, uses a blade to cut through the coating to the substrate. At least two cuts are made that intersect at 90 degrees to get a right angle lattice pattern. The cross-cut area is observed for any adhesion failure.
Key feature : To check to particle size distribution of powder coating at different sieves.
