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.Read more
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.
Microfibrillated Cellulose (MFC) is known for its high surface area and large amount of available functional OH groups that provide an outstanding chemical and physical interaction. In addition, due to the strong 3D network, MFC gives a new dimension of stability to various formulations like adhesives, coatings, emulsions, dispersions and so on. In our previous articles, we have already talked about different benefits of using MFC, such as open time or spraying thick formulations. With paints and coatings, the ability to control light transmission and reflection is important. Now your next question is: How can MFC affect this in any way? Follow me and let’s find out!
