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.
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.
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.
Suddenly, the new tax on pollutants in China, their ban on solvent based coatings for containers, and the city of Shanghais ban on solvent based coatings for exterior walls and wood ware has changed things. Do you want to know more on how to adapt in rapid market changes like these? In this topic Tuesday we are discussing this and showing you a couple of concrete examples to get your ideas start running. Don´t miss out on this weeks interesting discussion on saving business with the necessary level of innovation.
There are several solutions to improve strength performance, and there are new materials available on the market. But how do you find the reinforcement additives and agents that provides the benefits you are looking for? And can this be done inline with the increased demand for sustainability at the same time? Spend a couple of minutes on this weeks blog post, and get some inputs and ideas on what to expect from one of these new materials.
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.
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.
One of the benefits of highly fibrillated cellulose fibrils is its very high surface area. When 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.
Many reasons can lead to unstable formulations when you first start testing a new formulation or a new ingredient. Some are due to non-optimized use of ingredients such as stabilizers and others are due to formulation processing or incompatibilities. Sounds familiar? We might have good news for you.
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.
