Elevance Renewable Sciences Inc. (Woodridge, IL, and Waalwijk, Netherlands), a bio-based chemicals company, has signed a supply agreement with Stahl, a global leader in leather chemicals and high-performance coatings. The agreement enables Stahl to commercialize new coatings and polyurethane dispersions (PUDs) based on Elevance’s C18 polyol technology.
Stahl and Elevance have collaborated since 2016 to develop high-performing coatings using Elevance’s C18 polyols, a new class of bio-based polyurethane building blocks. Under the recent agreement, the companies will continue to develop new C18-based coatings with an emphasis on flexible substrates for various markets, including the demanding automotive segment.
The novel C18 polyol technology enables the development of hydrophobic and semi-crystalline bio-based coatings with improved hydrolytic stability while maintaining flexibility. Stahl will showcase these and other high-performing, bio-based technologies at the European Coatings Show in Nuremberg, Germany, this month.
“We have reached a significant milestone with our C18 polyol technology,” said Rusty Pittman, Chief Commercial Officer at Elevance. “Through our collaboration with Stahl, this technology is enabling bio-based coatings and PUDs with truly exceptional performance.”
Using a proprietary Nobel Prize–winning olefin metathesis technology, Elevance produces its specialty chemicals from plant oils. These chemical building blocks are leveraged in a range of applications, including detergents, coatings, personal care products, oil fields, agricultural chemicals and engineered polymers.
Stahl's Uwe Siebgens, Group Director, Performance Coatings and Polymers, added, “We are very happy to announce this partnership, that enables us to serve the high market demands of our customers with high-performance solutions, while improving the environmental footprint.
“Enabled by C18 polyol technology, we are broadening our portfolio of bio-based, high-performance polyols and polyurethanes in our Relca and Permutex water-based polyurethane ranges. Depending on the requirements, we have the opportunity to design products based on various kinds of plant oils.”
