- Viscosity, simply put, refers to a fluid's resistance to flow. In the context of HEC, it determines the thickness or thinness of the solution it forms when mixed with water. HEC's viscosity is directly proportional to its concentration - as the concentration increases, so does the viscosity. However, this relationship is not linear; instead, it follows a non-Newtonian behavior, meaning the viscosity changes with the applied shear rate.
