The viscosity (η, μ) describes the viscosity of liquids and fluids. It results from the internal friction of substances. A substance of high viscosity means that it is viscous and therefore less flowable. The dynamic (shear viscosity) and kinematic viscosity are also measures of the viscosity. If a substance shows high viscosity this means that the particles are strongly bound together. © 2017 SUBSTRATEC. All Rights Reserved.
