WebShear thickening corresponds to an increase of the viscosity as a function of the shear rate. It is observed in many concentrated suspensions in nature and industry: water or oil saturated sediments, crystal-bearing magma, fresh concrete, silica suspensions, and cornstarch mixtures. WebOct 15, 2001 · Ideally, use would be made here of a thickener with pronounced pseudoplastic properties. High shear forces, introduced as the coating passes through the spray nozzle, lower the viscosity enough to ensure good leveling of the spray droplets. Subsequently, the higher initial viscosity returns, and sagging is avoided.
