Shear thinning and the viscosity as a function of shear rate is a key parameter to control in products like for example water-based paint & coatings. Paint & Coating systems are often non-newtonian and the control of the shear thinning behavior is critical to avoid problems with sagging and leveling. Rheology additives like HEUR, HASE and Nanocellulose are often use to bring increased shear thinning performance and control to the paint & coating systems. In this Topic Tuesday, we are providing you with some more general information on how the shear thinning from nanocellulose works and how you can use it to improve the rheological performance from your products.
The technical application manager from the Cellulose Fibrils division in Borregaard, Otto Soidinsalo, in this video giving you the ABC of nanocellulose shear thinning behavior in addition to giving you some of the fundamental aspects of why this material is giving shear thinning properties.
