BASF, AkzoNobel, and Arkema have partnered to reduce the carbon footprint of powder coatings, achieving up to a 40% reduction in AkzoNobel’s super-durable Interpon D range. This is a series of architectural powder coatings designed for long-term outdoor use, particularly on building facades, window frames, and curtain walls. These coatings are based on polyester resins with enhanced weathering resistance, offering better durability against UV radiation, humidity, and environmental stress compared to standard powder coatings.
According to the companies, the improvement has been made possible through a combination of using supplier-specific product carbon footprint (PCF) data which are more accurate than generic industry average data and sourcing bio-attributed raw materials, such as BASF’s NPG ZeroPCF, a biomass-balanced version of neopentyl glycol (NPG) that is manufactured using renewable raw materials and renewable energy, resulting in a product carbon footprint (PCF) of zero.
Arkema incorporates these bio-attributed raw materials into low- and standard-temperature curing powder coating resins, further lowering CO₂ emissions across the value chain. A joint case study provides insights into methods, calculations, and the transition to more sustainable coatings.
The partners aim to expand collaboration and involve more stakeholders to accelerate decarbonization in the coatings industry.
