Hydroxyethyl cellulose (HEC) and Exilva microfibrillated cellulose (MFC) can both be used as rheology modifiers in a variety of industries to prevent sedimentation and settling. In this article, I review the ability of the materials to give a yield stress in a waterbased system and, because of that, provide anti-settling and anti-sedimentation behavior. Tune-in on a comparison between these two rheology additives.

Undesirable phenomena such as sedimentation and settling can often occur during the storage of paints. Therefore, a re-dispersion step is necessary which can mean additional cost. These challenges can be even more pronounced in high solid content formulations and so it is crucial to secure stability of those systems. To avoid these effects, rheology modifiers need to be added to paint formulations. So, I prepared some information for you and conducted a couple of tests with the rheology additive nanocellulose to show you how focus on yield stress will reduce sedimentation and settling.
