Cross Hatch Cutter (SH750)
The “Cross Hatch” test has been used widely in various forms in order to assess the adhesion of paint coatings.
The Cross Hatch Cutter is for assessing the resistance of paint coatings to separation from substrates when a right angled lattice pattern is cut into the coating, penetrating through to the substrate, it can also be viewed for adhesion between coating layers.
There are two ways to assess performance, as a Pass/Fail test or graded as described below.
Suitable for coatings applied onto flat surfaces and a thickness up to 250 microns.
A high precision machined wheel presenting 6 or 11 cutting blades with various spacing is mounted in a handle. The test
is carried out by performing one sets of (6 or 11 dependant on cutter selected) followed by another set of cuts at right angles to the first set.
The obtained lattice is either brushed or cleared by applying and removing adhesive tape. The results are then classified with reference to standard scales (see below for National Standards)
