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.

Topic Tuesday: How to perform with your oil-in- water-emulsion

By Mats Hjørnevik 11. September 2018

Mixing two liquids like oil and water is hard enough. At the same time keeping it stable, adds an additional level of difficulty in this challenge. And how can you reach the best performance on rheology and stability in the making of these emulsions? In this episode of Topic Tuesday, we are discussing the subject of emulsions; what are they, how do they work and how do we make them stable? Grab a coffee and joins us for a video session.

Research review August 2018: new nanocellulose findings

By Mats Hjørnevik 4. September 2018

This month’s research review has some interesting news from the world of nanocellulose. We have referred to a lot of interesting functionalities from this exciting material before, ranging from 3D printing to super reinforcer and rheology additives. Today, we are giving you the news of an interesting, and, I must admit, slightly unforeseen idea. It was uncovered in Asia. Dig in to this week’s blog post from the Exilva blog to read more.

3 great ways to exploit the large surface area of cellulose fibrils

By Mats Hjørnevik 28. August 2018

One of the benefits of highly fibrillated cellulose fibrils is its very high surface areaWhen the fibers are torn down to smaller and smaller fibrils, the surface area consequently increases, which leads to new properties and applications. Learn how its extreme water binding capacity, among other properties, may take your product to a new efficiency level.

My coating is seeing blocking issues; but what’s my option dealing with it?

By Mats Hjørnevik 24. July 2018

A familiar problem for producers of coatings and polyolefins is what literature calls blocking. When blocking occurs, it is the coatings ability to create adhesion to itself that causes the problems. There are many available technologies for avoiding this, in which some are synthetically derived, and others are derived directly from nature. Could a bio-based alternative give you the effect you are looking for? If you are looking for some ideas, this is the blog post to read.

Research Review June 2018: new technology is being created, and cellulose fibrils is participating

By Mats Hjørnevik 17. July 2018

Cellulose fibrils have been written and talked about for years. A substantial amount of reports have been written prospecting all sorts of application areas. Based on its functionalities, it seems to be a good rheology modifier, a good stabilizer and it is showing substantial strength enhancement. But is there any proof to the pudding and where do we find the latest developments? I have tried to gather a couple of relevant examples for you, which to me are fairly new developments. Dig into this week’s blog post to find out what they are!

How to improve your organic solvent system with a bio-based alternative

By Mats Hjørnevik 12. June 2018

Bio-based is on everyone's lips these days, and there are a high number of initiatives going on in innovating new product systems with a bio-based background. In this post I will give you a sneak peak into the improvement of an organic solvent system, using a biobased addtive as an example. Cellulose fibrils is a green and environmentally friendly material that consists of a complex three dimensional network of cellulose microfibrils.

It is well known that cellulose fibrils , because of its high surface area and many available hydroxyl (OH) groups, has a high affinity for water. This result in a material with very high water holding capacity that forms strong gels in water at low concentrations. Since cellulose fibrils is so fond of water, it might be easy to think that the material would not perform well if it was dispersed in other solvent systems. However, this is far from the truth!
