Cross hatch testing
WebAdhesion testing equipment is used to measure the force required to separate two surfaces. This type of testing is often used in the manufacturing and construction industries to determine the strength of adhesives. There are a variety of adhesion testers on the market, but all operate by applying a known force to a sample and measuring the ...

WebCross Hatch Method This basic and very subjective test method involves the user cutting an “X” through the coating, down to the substrate, using a sharp utility knife. The blade of the knife is then used to determine how easily the coating lifts off the substrate at the … WebRepeat the test in two other locations on each test panel. For large structures make sufficient tests to ensure that the adhesion evaluation is representative of the whole surface. Peel Angle and Rate The standard requires that the free end of the tape be removed rapidly at as close to a 180° angle as possible.

This is done by scoring the surface with a razor blade in a checkerboard or tic-tac-toe pattern. 4. Apply pressure-sensitive tape to the cross-hatching. 5. Remove the tape from the substrate. If not paint comes off with the tape, then adhesion is good.
WebThe cross hatch test is a visual comparison method for paint and powder coatings up to a thickness of 250µm (10mils) which is fast and easy to use. The coating is cut into small squares, thereby reducing lateral bonding, and the coating adhesion assessed against ISO 2409 and ASTM D 3359 or Corporate Standards. WebProduct Description.
