Steel Bar Scratch Tester

The steel bar cross-cut tester is used to detect coating adhesion. Its principle involves cutting the coating to form a grid pattern and observing the degree of coating peeling to assess the bonding strength. It serves to evaluate the bonding performance between the coating and the substrate and is applied in fields such as construction and industrial corrosion protection.
Selection
When selecting, consider the hardness of the substrate to match the specification of the cross-cut knife, the coating thickness determines the cutting spacing, choose manual or electric based on testing frequency, refer to national standards to determine the cross-cut dimensions, and account for environmental humidity effects by equipping with a temperature and humidity meter.
