Cross Hatch Cutter
The CROSS HATCH CUTTER for testing Coating Adhesion is a precision cutting tool made up of the specially designed handle and precision, multi-toothed cross-cut blades. Cross Hatch Adhesion Testing is appropriate for testing the adhesion of thinner coatings applied to flat and relatively smooth flat surfaces. Correct tooth spacing is determined by the thickness of the coating to be tested.
Cross Hatch Cutters may be purchased alone or in kits, and a variety of cross hatch blades are available for different paint applications.
ASTM D3359-09E2 Test Method B for Cross Cut Tape Test specifies the following:
-
dry film thicknesses < 2.0 mils (50 µm) cuts should be 1 mm apart, with eleven cuts made
-
dry film thicknesses 2.0 to 5 mils (50 - 125 µm), cuts should be spaced 2 mm apart, with six cuts made
-
dry film thickness thicker than 5 mm should be tested using D3359-09 Test Method A
The complete Cross Hatch Cutter Kit includes the cutter handle and one blade, pull-off adhesive tape, flaking brush, illuminated magnifier, hex wrench, and instructions in a plastic case. Cross cut testing kits conform to ASTM Test Method D3359 for coating adhesion testing.
Available blades:
11 - toothed: 1 mm spacing 1.5 mm spacing
6 - toothed: 1 mm spacing 2.0 mm spacing 3.0 mm spacing
