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.

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.
Paint manufacturers have been formulating paints containing microspheres in many years. Formulators can use microspheres to increase the solid content of a coating while maintaining the proper application and flow characteristics. Higher solids can reduce volatile organic compounds (VOCs), shrinkage and drying time. But there can be problems with settling and sedimentation, as well as floating of the microspheres. In addition, cost of certain types of microspheres can be high. In this article I will show you how the microfibrillated cellulose technology can give anti-settling and anti-sedimentation of microspheres, as well as enabling you to choose less expensive microspheres and obtain the same performance, which typically has been associated with more expensive types.
The pursue for a more efficient and increasingly EHS improved way of incorporating microfibrillated cellulose into polymers for polymer melts (thermoplastics) has been going on for years. Thermoplastics are an important source for many final products and applications. By introducing microfibrillated cellulose into polymers by the means of liquid suspension, Gneuss have been able to avoid the agglomeration of powder form similar particles, as well as improve the EHS profile of such a process.
Long-standing policies towards research and development no longer support manufacturers’ success, as mergers and globalization continue, due to: 1) Demands for bigger profits from investors who are distant from the business reality; 2) Bigger investment in innovation needed to give future success; 3) Shortening timescales as globalization introduces pressures from BRIC economies.
Modified polyurea and Exilva Microfibrillated cellulose (MFC) can both be used as rheology modifier 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 & anti-sedimentation behavior. Tune-in on a comparison between these two rheology additives.
Clay (including montmorillonite and bentonite) additives and Exilva microfibrillated cellulose (MFC) have a lot in common since they both can be used as rheology modifier in different industries. However, there are also clear differences. In this article, I will review the ability of the materials to provide yield stress and subsequent anti-settling & anti-sedimentation benefits. Tune-in on a comparison between two of the most potent anti-settling & anti-sedimentation additives available.
Exilva microfibrillated cellulose and fumed silica are both used for controlling the rheology of liquid systems, such as anti-settling and anti-sedimentation. But when we are comparing the two technologies, we also see differences. In this article, we will show you how the microfibrillated cellulose and fumed silica builds yield stress, and how they consequently can give good anti-settling and anti-sedimentation benefits.
Surfactants are present in most consumer products. The most familiar examples are shampoos, hand wash products and cleaning products in general. Switching to sulfate free surfactants improves the environmental profile, but can be a challenge. Let me show you a way to this.
I will demonstrate that one can use cellulose fibrils to thicken and stabilize formulations with foam forming surfactants. The most important point to remember when preparing such formulations is to avoid foam formation during the incorporation step of surfactants with the cellulose fibrils.
What is heat of hydration, and how does it affect the settling and curing phase of the concrete? Learn more about different types of concrete cracking, why they occur - and preventative measures and repair methods for fixing it in this Topic Tuesday. Hint: there are bio-based alternatives available!
