Cracking thickness test board

The cracking thickness test board simulates the drying and shrinkage process of coatings by scraping the sample onto a standard grid substrate. After drying, the grid pattern induces cracking in the coating, and the crack resistance is determined by comparing the crack morphology with a standard reference chart. It is used for flexibility testing and quality control of coatings and inks.
Selection
When selecting, ensure the substrate thickness matches the testing standards, and the grid size corresponds to the applicable thickness range of the coating. The metal plate should be flat and free from deformation, with galvanized steel or stainless steel as the preferred materials. The grid pattern should be clear and uniform, with no burrs at the edges. Consider the viscosity and drying characteristics of the sample to choose the appropriate specifications.
