Why cellulose fibrils (microfibrillated cellulose) will make a difference in coatings

Coating performance is often very complex, and can depend on the coating system itself, substrate to be coated, conditions during coating etc. Increasing the performance is often a lengthy process with multiple tests on wet paint performance and dried coating performance. Key aspects of wet paints can be control of rheology, and for solid coatings the ability to improve endurance. Are there technologies available for aiding on the key aspects? For sure. Are there new sustainable additives which can improve the new water borne technologies? Let me show you an example of exactly that in this blog post.

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 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.

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

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?

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.

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

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.

How to counteract formulation settling issues

Everyday life is full of formulations containing solid particles, pigments, beads or fillers. Depending on the application, the formulations may have a varying amount of solids. Common challenges with high solid content formulations are the settling of heavy particles or the floating of lighter ones. Therefore, it is important to ensure the stability of the solids suspended in a formulation. Especially those with high particle loading such as a coating formulation with matting agents, UV filters and other solids.

Why do we use microspheres when formulating paints?

Paint formulators face many challenges in today’s market, and are continuously in search of new innovative raw materials to satisfy the needs of their customers. In an effort to reduce cost, improve technical properties, and fulfill more stringent environmental regulations, chemists have started to look toward a class of products known as microspheres.

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

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.
