This Test describes a method for assessing the resistance of paint coatings to separation from substrates when a right-angle lattice pattern is cut into the coating, penetrating through to the substrate. The property measured by this empirical test procedure depends, among other factors, on the adhesion of the coating to either the preceding coat or the substrate. The method described may be used either as a pass/fail test
The Cross test is used to access adhesion of paint coating. This cutter having single cutting blades. Test is carries out by performing crossed cuts at right angle. After clear with adhesive tape or brush…..
