rheology

A term pertaining to viscosity behavior, e.g., the viscosity of an adhesive under conditions of shear, or the plastic flow properties of an adhesive. Rheological behavior may be thixotropic, where viscosity decreases greatly with shear; dilatant, where viscosity increases greatly with shear; or Newtonian, where viscosity is directly proportional to shear.
