Three reasons why water-borne product systems are taking over

By Mats Hjørnevik 4. December 2018

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 cellulose fibrils / nanocellulose

By Mats Hjørnevik 13. November 2018

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 cellulose fibrils/nanocellulose technology.

How can i control the rheology of my concrete better?

By Tania Risson 30. October 2018

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

By Mats Hjørnevik 23. October 2018

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.

How to compare rheology additives: the example of nanocellulose/Cellulose fibrils and HEUR

By Mats Hjørnevik 16. October 2018

As a researcher, to have an overview of the alternatives available in your area of profession is of importance. In the landscape of rheology, new alternatives are emerging. In my short review today, I will grasp on the subject of similarities and potential synergies between two of the candidates you should note down: nanocellulose and hydrophobically modified ethoxylated polyurethanes (HEUR). Here are my hints and tips  on how to understand these two technologies better.

[VIDEO] Topic tuesday: Sag vs. leveling. Can you handle 'em both?

By Mats Hjørnevik 9. October 2018

A fast viscosity recovery is good, and some times crucial, but that would also affect the leveling, right? In this weeks Topic Tuesday, we discuss how you can cope with the issue of getting fast recovery - and avoid sag - while getting your coating layer in level. We may also have some exciting ideas for you if you have problems with cracking.

High performance and durability with greener tire tread

By Otto Soidinsalo 2. October 2018

There is a growing interest to increase the portion of bio-based components in various consumables. We have previously discussed about the challenges to incorporate microfibrillated cellulose (MFC) into composite materials with hydrophobic matrixes, such as PLA. Today we will take a step even further and see how cellulose fibrils can support the development of more environmentally friendly tires with high performance and durability.
