What is thixotropy?

Thixotropy describes the recovery behavior of plastic and pseudoplastic systems when subjected to shearing stress (e.g. mixing). The recovery in such systems is delayed due to breakdown in the structure of the material. This breakdown requires time for original structure and viscosity to be recovered after the applied shearing stress is stopped.

The magnitude of thixotropy can be measured for plastic materials.
