Cross Hatch Cutter Elcometer By Caltech Engineering Services

The Cross Hatch Cutter will allow 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. Coating is cut into small squares using cross cuts and reduces lateral bonding, and the adhesion assessed against ISO, ASTM or customer specifications. 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, one cutting pass makes 6 cuts in the coating, a second pass at 90A makes a square lattice pattern. Apply special adhesive tape over cut section and within 5 minutes remove tape. Classify the cut area according to the relevant national standard classification guide. This test conforms to BS 3900:E6, ASTM D 3359, BS/DIN EN ISO 2409

The cutting blades are ground onto 6 cutting sides, so that when one cutting side becomes blunt there are a further 5 cutting sides to use. Therefore giving a 1/3 rd extra life over conventional 4 sided models.
