Adhesion cross-hatch is a tool used to evaluate the adhesion of coatings, usually used for coating quality inspection and coating process control. It evaluates the adhesion of a coating by scratching a series of grid patterns on the surface of the coating, using an appropriate tool to cover the scratched area with tape, and then quickly removing the tape.
Adhesion cross-cuts can be used for on-site testing during the coating process, or for coating research and quality control in a laboratory environment. It is an easy and fast method for evaluating the adhesion of coatings and provides qualitative or semi-quantitative information on the bond strength between coatings and substrates.
