Cross Hatch Adhesion Tester or Adhesion Testers verify that both surface preparation and coating application are within specification.
From the largest man-made structures to the smallest household appliances, most manufactured products have a protective or cosmetic coating. Premature failure of this coating can, at the very least, result in additional costs of rework.
Adhesion testing after the coating process will quantify the strength of the bond between substrate and coating, or between different coating layers or the cohesive strength of some substrates. Routine adhesion testing is used as part of inspection and maintenance procedures to help detect potential coating failures.
Elcometer offer a highly comprehensive range of Adhesion Gauges designed specifically to meet your requirements.
Cross Hatch Adhesion Tester or Cross Hatch Cutters
Using this Cross Hatch adhesion tester is a fast, low cost, visual comparison method for paint and powder coatings up to a thickness of 250µm in order to evaluate the coating adhesion. The coating is cut into small squares, thereby reducing lateral bonding, and the coating adhesion assessed against ISO, ASTM or Corporate Standards.
| Description | IS0/BS/DIN | ASTM |
| The edges of the cuts are completely smooth, none of the squares of the lattice are detached | 0.5 | B |
| Detachment of small 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. Across cut area significantly greater than 35% but not significantly greater than 35% is affected | 4 | 1B |
| Any degree of flaking that cannot even be classified by classification 4/1B | 5 | 0B |

Measure on large or small panels by quickly changing the position of the guide wheel using the hexagonal wrench provided. Each cutter wheel consists of 8 cutting faces. When one face becomes worn, rotate the cutting wheel to the next face. The Elcometer 1542 Cross Hatch Cutter is available with three different cutter spacings 1, 2 & 3mm for a range of coating thickness. The Elcometer 1542 is available on its own (Basic Kit) or as a Full Kit which … Read More
The Elcometer 1540 Adhesion Tester is a simple instrument for quickly determining the coating adhesion of a large variety of paints up to 50µm thickness. Made from steel, this cross hatch gauge has 11 tapered teeth with 1mm spacing. Two sets of lines are cut at right angles to obtain a pattern of 100 squares. Classification of Cross Hatch Test Results Surface Typical description of result The edges of the cuts are completely smooth, none of the squares of the … Read More
