Drying and Cracking Tester

The drying and cracking tester simulates the material drying process to detect the tendency of coatings or films to crack during water loss and shrinkage. It records parameters such as cracking time and number of cracks, which are used to evaluate the crack resistance of products like architectural coatings and inks, guiding formulation adjustments and process control.
Selection
When selecting a drying and cracking resistance tester, it is essential to consider the compatibility between the sample type and size with the instrument's specifications. The temperature control accuracy must meet the drying requirements of the material. The data acquisition system should accurately record the crack development process, and the operation interface should be simple and user-friendly for daily testing. Additionally, compatibility with testing standards for similar materials should be taken into account.
