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!

Looking for a rheology additive for a waterborne system? here are some hints on what to look for (and how to find a bio-based one)

By Mats Hjørnevik 5. June 2018

This week I would like to discuss water-based systems where the challenge is to apply the product effectively on a surface. This can be true for a high number of products ranging from coatings, adhesives, composites (for instance plastics), materials for 3D printing, deicing products and so on. The downstream processing and application of the product is by medium or high shear equipment, meaning either a roller, brush, a spray or the like. This calls for a shear thinning rheology system to stabilize the formulation and give the correct viscosity at each step.

Trouble with cracking during drying of your coating, adhesive, putty or other products?

By Mats Hjørnevik 22. May 2018

One of my favorite characteristics of the cellulose fibrils is its behavior when drying or involved in the drying process of a product system. I have learned through some of our conducted tests that cellulose fibrils can act in an interesting and often beneficial way towards obtaining desired end product characteristics. Most of the examples on how the fibrils influence the drying are related to coatings. I however believe that similar behavior is possible to observe in application areas where a tight control of dry-out properties is desired. Evaporation of solvents is often the main technique for drying in many applications. I will therefore focus my blog post this time on this specific drying technique. Let me share some very interesting insights into why cellulose fibrils are improving the products upon drying.

How to improve art conservation by utilizing the technology advantage

By Mats Hjørnevik 15. May 2018

OK, so this case fascinated me a great deal. I have previously learned a lot on film forming properties, oxygen barrier properties and other related topics to this in the past. But recently I learned that the properties from microfibrillated cellulose and cellulose fibrils is starting to show potential in art preservation or conservation. But how does this take place, and what’s the main functionalities behind all this? I spent some time researching the subject, and today I am sharing my findings with you. Some key words: stability, transparency and mechanical strength. Dig in to learn more!

Why should I use cellulose fibrils in coatings?

By Mats Hjørnevik 17. April 2018

It is important for producers of coatings to control flow and stability. The way to do this in water borne systems has typically been a work for synthetically derived additives, water-soluble cellulose derivatives or clays. Can cellulose fibrils do anything new for you?

Research review March 2018: new topics from the world of cellulose fibrils

By Mats Hjørnevik 3. April 2018

Continuously following the world of cellulose fibrils and the development is both dynamic and interesting. A lot of new inventions are taking place, based on the cellulose fibrils. We have given 3D printing a quite high focus in the last couple of reviews, but this week there are two other news items on the list: composites made from cellulose fibrils. Dig into this week’s research review to find out more on what might possibly be the next generation of composite materials.

The past, present and future of performance coatings: can waterborne systems improve it?

By Mats Hjørnevik 27. March 2018

The performance coatings sector has seen decades of development to protect installations and transportation equipment. The sector has been highly dominated by solvent based systems and these systems have seen incremental innovations for a long period of time. The end-user demands for these systems have been set in a context of a world in an ever-changing environment: high pressure on efficiency, increased globalization and international trade, as well as the period of increased climate focus. So how is this world going to look in the near future? In my attempt to share thoughts on this subject, I will focus on the rheology system, how its currently being solved and how it can be solved with alternative, more environmentally friendly technologies in the future.

Topic Tuesday: A talk with one of the pioneers in nanocellulose and cellulose fibrils

By Mats Hjørnevik 27. February 2018

Dr. Julien Bras from the Grenoble Institute of Techonology has been working in the field of cellulose fibrils, nanocellulose and microfibrillated cellulose for two decades. He is considered as one of the pioneers on the concept as we know it today. In this 5 minutes chat with Dr. Bras, we touched upon several topics regarding this new material. Do not miss out on the opportunity to listen in to Dr, Bras ideas one some of the directions the cellulose fibrils and nanocellulose will be taking in the future.
