Our bio-based polymer technologies
Our latest innovation is a portfolio of bio-based polyol and polymer technologies. To turn the tide on global exhaustion of resources, we are creating high-performing resins based on non-limited raw materials. This way, we aim to reduce the environmental footprint with responsible production and products. This is vital, as the ecosystem has been brought to a breaking point where striving for circularity is the only logical step.
Raw materials as the basis of sustainable chemistry
The raw materials we use are key as our global consumption is now exceeding the earth can reproduce and our emission of carbon dioxide can no longer be absorbed. It is time for a change and that is why Stahl Polymers, as part of the overall Stahl effort, is committed to sustainable chemistry as is underlined by our bio-based portfolio. From biomass, generated from renewable sources, like rapeseed oil, wheat, waste, algae and soy, we create biopolymers for our water-based binders and coatings.
Bio-based polymers without compromise on performance
To change towards a circular industry, we need to work together and rethink, redesign and rewire polymeric technologies. That means stepping out of our comfort zone, look for partnerships and cooperate because to change the world, we need to work together and rethink, redesign and rewire how we operate. This is an ongoing trajectory of innovation, starting from solvent-borne coatings to water-based, label-free and now bio-based resins that offer the same performance while using more responsible raw materials.
Cooperation is key for a successful transition
Our journey towards more sustainable solutions for our customers is hardly at an end. There are many possibilities of bio-based polymer coatings to explore and cooperation is the key to unlock new possibilities. We work with Elevance to create a new class of bio-based polyurethane building blocks based on their C18 monomer technology. As partners, we continue development on C18-based coatings, with a focus on resins for the demanding automotive segment, architectural coatings, coil & industrial metal and printing & packaging industries. This novel polyol technology enables us to develop hydrophobic and crystalline bio-based polymer coatings with improved hydrolytic stability, while maintaining the desired flexibility.
Bio-based resins, polyols and binders product overview
We offer a variety of bio-based polyols and resin technologies, which provide the desired performance qualities with a lower environmental footprint. This enables coating and paint manufactures to add the best properties to coatings, without compromise on sustainability.
