March 3, 2026 – Stahl, a global leader in specialty coatings for flexible materials, has announced the global launch of PermUCell™, its next‑generation water‑based, DMF‑free coagulation technology for the production of high‑quality polyurethane substrates.

Following successful adoption by key manufacturing partners across Asia, the world’s leading hub for footwear and synthetic materials production, PermUCell™ is now fully available to manufacturers worldwide.

Driving the Transition to High‑Performance, DMF‑Free Materials

PermUCell™ offers a compelling solution for high‑performance footwear manufacturers, enabling them to achieve sustainability goals without compromising quality or efficiency.

This fully DMF‑free technology is compatible with existing coagulation production lines, reducing environmental impact while meeting leading brands’ requirements for aesthetics and durability.

Its exceptional softness, breathability, and flexibility deliver superior comfort and a premium wearing experience for end consumers.

Following successful industrial‑scale implementation with partners in Asia and Europe, PermUCell™ has proven its readiness for global deployment.

Empowering Customers with Global Technical Support

Stahl’s water‑based coagulation portfolio is backed by a worldwide network of technical experts and application excellence centers.

This ensures global customers receive hands‑on guidance for:

• Production setup and parameter optimization
• Production line integration and scale‑up
• Material performance tuning to brand specifications
• Troubleshooting and continuous improvement

“Our goal is to support customers in a smooth and confident transition to cleaner coagulation technologies, underpinned by stable process control and consistent technical performance,” said Montse Pous, Global Technical Manager for Synthetic Materials at Stahl.

Lidia Martínez, Global Marketing Manager for Synthetic Materials at Stahl, added:

“With PermUCell™ and the support of our global technical team, manufacturers can accelerate their sustainability journey and phase out DMF without compromising performance or productivity.”
