CH-Polymers is focusing on developing sustainable solutions to all industries we serve. Now the focus is the paint industry and how to improve sustainability of various coatings. The 23rd SLF Congress will be held in Drammen, Norway on September 21-22, 2022. A technical presentation will be given by our very own Gun Lundsten. The topic is “Bio-based, Bio-degradable or Sustainable Binders?” Or all of the three? As a waterborne polymer dispersion producer for both paper and packaging, paint and coating as for non-woven applications we are trying to find solutions for all these three needs. But bio-based doesn’t necessarily mean that the solution is bio-degradable – or even sustainable! And a sustainable solution doesn’t necessarily need to be bio-based. In this technical paper we will philosophize around these definitions. We will also report on our findings of the differences in sustainability values and technical performance of waterborne binders when using bio-mass compared to bio-based monomers. Furthermore, we will present our concept of partly bio-based binders developed for paints. Prepared by Gun Lundsten and Teemu Piesanen
When life gives you lemons – make lemonade During unstable times we all need something that will give us that extra boost. People spend more time at home and with the bright spring light shining in it is easy to detect places that would benefit from a touch of decoration. The Painting Season 2020 is starting, so go out and buy (or, actually, please order online) a can of paint. Painting is easy and also something that the whole family can participate in. You see the results immediately and the small improvements or the real masterpieces can be enjoyed by family and friends in all the coming years. Do-It-Yourself! There are a few things to keep in mind though: paint at correct temperature, read the instructions on the paint can do not paint in direct sunlight paint on dry substrate Even if you do everything right, your paint should also be up to the task. Waterborne polymers used as binders in exterior paints give your painting project long time protection. When we are developing our binders, we monitor: flexibility liquid water permeability wet adhesion exterior durability water vapour transmission i.e. “breathing” of the paint …and many other features like dirt-pick-up […]
Purpose of this project was to develop waterborne polymers that are suitable for polyethylene and polypropylene surfaces. Main research areas were polymer morphology use of specialty monomers Teemu at work in CH-Polymers’ laboratory ”I made my Master’s thesis for CH-Polymers, as part of their Adhesion project. I can certainly say that the project was interesting and it gave me and CH-Polymers additional information about morphology and adhesion.” –Teemu Piesanen, M.Sc. It is known that achieving adhesion to inert polyolefins is difficult without any surface treatment. Contact angle measurements and other adhesion analysis methods were used to characterize the performance of the polymers. As a conclusion a 40 % increase in adhesion was achieved. This is a great result in our multipurpose products. Teemu will continue his work at CHP laboratory. We are keen to know what he comes up with next! “Understanding the interactions between different materials opens brand new ideas to be applied in our product development. ” -R&D Manager Gun Lundsten
SLF Congress in Copenhagen 27.-28.9.2018 Better exterior house paints A study of Nordic exterior house paints, all given good scores in a test by Folksam Insurance company, will be presented at the SLF congress in Copenhagen. One of the key findings is that there are many ways to formulate a high-performance house paint. A balance of several features such as adhesion, water absorption and flexibility is greatly influenced by the choice of the binder. An open mind and new approaches to formulation are a good starting point when formulating new paints using the latest technology. Gun Lundsten will demonstrate to you how to minimize undesirable features such as water uptake while allowing the film to breathe. This opens up new opportunities to protect our beautiful Nordic wooden houses. This technology has been developed and tested in Finland for demanding Nordic conditions.

Even the toughest wine and coffee stains are easy to remove when the paint is formulated with CHP 536. Watch this demonstration by local students to see for yourself! Did you know that […]
