thixotropic index definition
Thixotropic Index (TI) Definition - What does Thixotropic Index (TI) mean? This is a ratio between the slow speed viscosity to the high speed viscosity of a non-Newtonian body. It is obtained from dividing the viscosity number at low speed by the viscosity number at high speed of a given fluid. It therefore defines how well the fluid will hang or resist sagging under gravity.
