[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.

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.

How to use and understand cellulose fibrils? The practical experience from Covestro

Our blog post of the week is today a really exciting one! We have been so fortunate to interview Peter Küker, who is a technical manager at Covestro in Germany. Peter has been working with cellulose fibrils in a project at Covestro for some time, and today he is sharing his views and experience on utilizing the fibrils in some of the Covestro formulations for adhesives. Don't miss out on this opportunity to learn more about the actual experience of utilizing the effect from the fibrils on rheology, dispersion and material handling.

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

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.

Why should I use cellulose fibrils in coatings?

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?

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

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.
