| Résumé : |
Over the last few years, topics around health and environmental challenges and sustainability have gained further attention, especially amongst the younger generation. This mega trend is seen across ail industries globally, but is particularly visible for the automotive, chemical and manufacturing industries. Numerous new and revised regulations have been introduced to the chemical industry in different regions, including Europe, which has seen a number of revised regulations and reclassification of chemical substances, such as volatile organic compounds (V005), formaldehyde, acetaldehyde, titanium dioxide (T102) and several isothiazolinone limitations in the last two years.
2050 and form a more sustainable economy, with an action plan to boost the efficient use of resources by moving to a clean, circular economy and restore biodiversity and cut pollution. The European Commission expects all economy sectors to take action in investing in environmentally-friendly technologies, decarbonising the energy sector, supporting industry to innovate and ensuring buildings are more energy efficient. It is expected that there will be a renovation wave to modernise Europe's buildings, which presents a great opportunity to the paint and coatings industry. It is also expected that the other regions will put in similar efforts to drive for more sustainable growth and introduce various initiatives to improve the current environmental and climate situation. The UK, for example, has also recently announced its Green Homes Grant program to encourage home owners to make energy-saving improvements with financial support from the government.
With this trend in mind, Synthomer has developed a novel styrene acrylic binder with excellent water resistance, scrub resistance and hiding power, which potentially enables the paint and coatings industry to optimise binder and pigment dosage, resulting in paint property, carbon footprint and cost improvement. Formulations based on this new binder can also meet the 2018 criteria for the RAL UZ 102 label ("Blue Angel") in the category "Low Emission Interior Wall Paints' ln the following article, we detail our internai studies that enable the aforementioned savings by showing test resuits of paint formulations with a high pigment volume concentration (PVC) and within the gloss range of matt (<10 GU 85°) and dead matt (<5 GU 85°), which are popular in the DACH market (Germany, Austria and Switzerland). We will also elaborate resuits from formulations for mid-sheen gloss >10 GU 85° wall paint, often encountered in other European countries, such as France and UK. A market standard styrene acrylic polymer was used as benchmark in this study. |
