What is thixotropy?

Thixotropy is a property of certain materials, particularly gels and fluids, that allows them to become less viscous when subjected to stress or agitation, enabling them to flow more easily. Once the applied stress is removed, these materials gradually return to their original, more viscous state. This behavior is commonly observed in substances like some paints, clays, and biological fluids. Thixotropic materials are useful in various applications, including in the formulation of products that require ease of application while maintaining stability when at rest.
