Stahl, world leader in the specialty chemistry of coatings, processing and treatments, provides functionality, durability and comfort to many different materials used in everyday life. Although they may not realize it, millions of people around the world touch products with Stahl’s chemicals and coatings every day. Interested in our organization? The infographic below gives you a good first impression.
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.
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.
