Why Microfibrillated Cellulose can enable you to formulate paints with less expensive microspheres

1. October 2019

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.

[VIDEO] Topic Tuesday: Is bio-based becoming a consideration in construction industry?

We rely on well-proven construction technologies wherever we move around. The construction technologies have been developed for decades to make sure that we have long-living and safe infrastructure and buildings around us. But in a world moving in increasing speed towards more emphasis on lowering emissions and waste, how is the construction industry affected? And are there any ready-made bio-based solutions available?

Focus on sustainability is changing business!

We are starting to see major shifts towards increased focus on sustainability, with examples like the likely upcoming EU ban on single use plastics, and the Chinese environmental tax on solvent based coatings. Your company and its competitive advantage will be defined by the ability shown in adapting to this. I will in this blog post touch upon a subject that can be important to assess for you going forward.

Three reasons why water-borne product systems are taking over

You may have noticed that the number of waterborne systems has increased massively during the past decade. Waterborne systems, like paint and adhesives, where water is the main part of the product in many cases, are popular due to several factors. My goal with this article is to introduce you to what I believe are the three most significant aspects of the increased demand for waterborne product systems, focusing on coatings and adhesives.

Important rheological properties of Exilva microfibrillated cellulose

Rheology is the study of deformation and flow of material under stress, for example how easily material changes its form when it is pressed, or how easy it is to pump liquid in the pipes. Yield stress and viscosity are two importance aspects in the study of rheology and I will today exemplify this by using the Exilva microfibrillated technology.

How can i control the rheology of my concrete better?

Concrete products are a complex mixture of chemicals, fines, and heavy particles. It's always challenging to control the stability, flow and strength of it. Many admixtures have been created to overcome these challenges, often containing synthetically derived performance additives. I will here try to give you some input of one of the new technologies and how it affects various parameters in the concrete.

How to compare rheology additives: The example of nanocellulose/cellulose fibrils and HASE

For decades, producers of fluid materials have used HASE as the fundamental technology to control flow. How can new technologies complement this work horse of rheology modification? This week I am trying to uncover the key aspects of the HASE technology and give you ideas on the HASE technology in relation to the world I am familiar with: nanocellulose and cellulose fibrils.
