Cross Hatch Cutter

The Cross Hatch Cutter is a multi-blade cutting tool which 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 1 mm Cutter is suitable for coatings under 60 microns. The 2mm Cutter is suitable for coatings over 60 microns. The hardened tool steel cutting blades are precision-ground with 6 cutting sides, so that when one cutting side becomes blunt there are a further 5 cutting sides to use. The Adhesion Test Tape has an adhesive strength of 9.5N per 25mm width and is transparent to ensure correct adhesion to the coating.
