Test procedure

Place the cross-cut tester on the test object, apply soft pressure and pull the device towards yourself in even movements in order to make parallel cuts with a length of approx. 20 mm. Apply enough pressure to make sure that you reach the next layer or carrier material.
Place the cutting tool on the sample at 90° to the first cut and repeat step 1 to create a lattice pattern on the coating (Figure 1).
Use a brush to remove dirt from the lattice and inspect to ensure the cuts have penetrated all the way through the coating (Figure 2).
Remove and discard two complete turns of adhesive tape. Remove an additional length of tape at a steady rate and cut a piece approximately 75 mm from this length.
Place the turns in the middle of the lattice and use a pencil eraser to straighten the adhesive tape. (Image 3)
Remove the adhesive tape carefully in a 180 ° angle. (Image 4)
Analysieren the result.
Repeat the test in two more positions.

Note: If you would like more information on this test method, please have a look at the relevant standard (ISO/ASTM).

Analysis

Coating adhesion can be assessed by comparing the lattice of cuts with ASTM or Corporate Standards. The ASTM standards are reproduced in the following table.

PCE Instruments PCE-CRC 10 Adhesion Tester - comparing the
lattice | The edges of the cuts are completelysmooth; none of the squares of the lattice is detached.| 0| 5B
---|---|---|---
Detachment of flakes of the coating at the intersections of the cuts. A cross cut area not significantly greater than 5% is affected.| 1| 4B
The coating has flaked along the edges and/or at the intersections of the cuts. A cross cut area significantly greater than 5%, but not significantly greater than 15% is affected.| 2| 3B
The coating has flaked along the edges of the cuts partly or wholly in large ribbons, and/or it has flaked partly or wholly on different parts of the squares. A cross cut area significantly greater than 15%, but not significantly greater than 35%, is
affected.| 3| 2B
The coating has flaked along the edges of the cuts in large ribbons and/or some squares have detached partly or wholly. A cross cut area significantly greater than 35%, but not significantly greater than 65%, is affected.| 4| 1B
Any degree of flaking that cannot be classified even by classification 4 (1B).| 5| 0B
