Elevance and Stahl collaborate on bio-based coatings

In Illinois, Elevance Renewable Sciences, Inc., producer of novel, high-performing specialty chemicals from renewable feedstocks, has signed a supply agreement with Stahl, global leader in leather chemicals and high-performance coatings. The agreement enables Stahl to commercialize new coatings and Polyurethanes 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.

This novel C18 Polyol technology enables the development of hydrophobic and semi-crystalline bio-based coatings, with improved hydrolytic stability, while keeping the desired flexibility.

“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.”
