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