Cross Hatch Cutter is used to conduct the adhesion test of coatings after full curing of paint film. It provides an instant assessment of the quality of the bond between the coatings and the substrate.
Test is carried out by performing cross cuts at right angles. Clean the test area with a brush after that adhesive tape is pasted by pressing with your thumb and pulling it off. Then observe for any adhesion failure. If the film does not remove from the substrate then it means that the adhesion test is passed by the coating.
These cross hatch cutters are used in paint and coating, pipe, automobile, steel and cosmetic industries for adhesion tests.
Cross hatch cutters are available according to IS , ISO, ASTM standards.
Thickness of the coating determines which type of cross hatch cutter is to be used for conducting the test.
|Coating Thickness||Range||No. of teeth||Gap between each teeth (mm)|
|Upto 60 µm||1 mm||11||1|
|From 60 – 120 µm||2 mm||6||2|
|Above 120 – 250 µm||3 mm||6||3|
Standard: ASTM D 3359, IS 101 (Part 5 /sec.2), ISO 2409
