Why Microfibrillated Cellulose can enable you to formulate paints with less expensive microspheres

1. October 2019

Paint manufacturers have been formulating paints containing microspheres in many years. Formulators can use microspheres to increase the solid content of a coating while maintaining the proper application and flow characteristics. Higher solids can reduce volatile organic compounds (VOCs), shrinkage and drying time. But there can be problems with settling and sedimentation, as well as floating of the microspheres. In addition, cost of certain types of microspheres can be high. In this article I will show you how the microfibrillated cellulose technology can give anti-settling and anti-sedimentation of microspheres, as well as enabling you to choose less expensive microspheres and obtain the same performance, which typically has been associated with more expensive types.

Gneuss enabling the use of Microfibrillated Cellulose in polymer melts for thermoplastics

The pursue for a more efficient and increasingly EHS improved way of incorporating microfibrillated cellulose into polymers for polymer melts (thermoplastics) has been going on for years. Thermoplastics are an important source for many final products and applications. By introducing microfibrillated cellulose into polymers by the means of liquid suspension, Gneuss have been able to avoid the agglomeration of powder form similar particles, as well as improve the EHS profile of such a process.

Topic Tuesday: Next generation gypsum boards

Gypsum boards (plasterboard/drywall) are a very commonly used product in the construction industry. Currently, the production of the boards is a labor-intensive, CO2 producing and energy consuming process with the need for many synthesized additives to retain the flow, strength and setting profiles. What if you could change that?

The Challenges of Climate Change and the Effect On the Construction Industry

Over the last century, human activities have been affecting the global environment, most noticeably with the general increase in greenhouse gases, such as carbon dioxide (CO2). This rise in greenhouse gases has mainly been due to the upsurge in fossil fuel consumption over the last fifty years. This consumption has had a knock-on effect with global temperatures, with a general increase of 1°C over the last century and this is projected to rise by 2°C over the next century.1 This increase in temperature has also affected climate change by giving more extreme weather conditions. But how has this affected the construction industry? Have we been developing alternatives that could point us in a more bio-based direction?

[VIDEO] Topic Tuesday: Is bio-based becoming a consideration in construction industry?

We rely on well-proven construction technologies wherever we move around. The construction technologies have been developed for decades to make sure that we have long-living and safe infrastructure and buildings around us. But in a world moving in increasing speed towards more emphasis on lowering emissions and waste, how is the construction industry affected? And are there any ready-made bio-based solutions available?

How can i control the rheology of my concrete better?

Concrete products are a complex mixture of chemicals, fines, and heavy particles. It's always challenging to control the stability, flow and strength of it. Many admixtures have been created to overcome these challenges, often containing synthetically derived performance additives. I will here try to give you some input of one of the new technologies and how it affects various parameters in the concrete.
