Cross Hatch Cutter For Testing Coating Adhesion
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 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.
To choose a right cutter.
Operation When using the 1mm spacing with 6 tooth blades, with the knife edges downward, pull the tool over the painted surface being tested; scratching the coating to the bottom. A second crosswise cut (at an angle of 45° or 90°) will produce a ruled area comprising 25 squares or diamonds. Evaluate the appearance or behavior of the coat of paint after some vigorous strokes with the stiff brush provided, or scratching with a fingernail (partial or complete flaking or peeling, no change, etc.). Also note the condition of the substrate (sand-blasted, primed or with a prime coat, degreased, pickled, etc.). Ordering.
