The Cross Hatch Cutter allows an assessment to be made of the adhesion resistance of coatings to separation from substrates when a right-angled lattice pattern is cut into the coating and penetrates through to the substrate.
The coating thickness determines the Cutter size used. The 1mm Cutter is suitable for coatings under 60 Microns. The 2mm Cutter is suitable for coatings over 60 Microns.
Simple operation, each Cross Hatch Cutter has 6 cutting blades spaced either 1mm or 2mm apart. Make one cutting pass through to the substrate. This makes 6 cuts in the coating. A second pass at 90° makes a square lattice pattern. Apply Adhesive Tape over the cut lattice section and within 5 minutes remove tape. Classify the cut area with the Viewing Lens according to the relevant national standard classification guide.
Multiple coatings can be tested for the assessment of the resistance to separation of individual layers of the coating from each other.
Precision-ground, hardened tool steel cutting blades with 6 cutting sides, so that when one cutting side becomes blunt there are a further 5 cutting sides to use.
Complies with International Standards: BS 3900 E6, ASTM D3359, DIN EN ISO NF 2409 and ECCA T-6.
Supplied in a Foam-Filled Carrying Case with a 3x Illuminated Magnifier and Adhesion Test Tape (25mm).
