5 MEASURING CROSS-CUT ADHESION
The cross hatch cutter scores through the coating right down to the next coating layer or down to the
substrate. Two cuts are made at right angles to each other resulting in a grid of small squares. Adhesion is
then assessed visually by comparing the grid of squares against ISO, ASTM or Corporate Standards.
5.1 SELECTING CUTTING BLADES
A range of cutting blades is available for different thicknesses and types of coating.
Cutter no.

Mount the cutting blades in positions 4 and 5.
5.2 ANALYSING THE RESULTS
Assess the coating adhesion by comparing the lattice of cuts with ISO, ASTM or Corporate Standards. ISO
and ASTM standards are reproduced in Table 1
