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.
