Stahl launches Syncros™: A new generation of sustainable crosslinkers for leather finishing
Waalwijk, the Netherlands, 17 June 2025, Stahl, the global leader in speciality coatings and treatments for flexible substrates, proudly introduces Syncros™, a novel generation of super-functional carbodiimide crosslinkers designed to bring high performance and sustainability to leather finishing. With the launch of this new patented technology, Stahl strengthens its commitment to providing environmentally responsible alternatives to traditional crosslinkers, while maintaining the highest levels of reactivity, efficiency, and durability.
Bridging the gap between performance and safety
Crosslinkers are essential in the coating process, enhancing the durability and performance of applications in performance coatings, packaging coatings and leather finishing. However, conventional crosslinkers such as aziridines and isocyanates pose significant health and environmental risks due to their toxicity, requiring strict handling precautions. Syncros™ introduces a safer, next-generation alternative for leather finishing that eliminates these concerns while delivering superior performance.
Sustainability and innovation in leather finishing
Developed through Stahl's cutting-edge R&D centers, Syncros™ XR-55-400 is designed for aqueous topcoats and basecoats, delivering outstanding resistance, flexibility, and efficiency. The key benefits include:
Low toxicity validated by external accredited laboratories
Free from carcinogenic, mutagenic, and reprotoxic (CMR) substances
Pot-life 4 to 6 hours, can be longer depending on the mixture
Enhanced durability, with high resistance to abrasion, stains, and chemical exposure
Non-yellowing properties for long-term aesthetic preservation
Strong adhesion capabilities, ensuring superior coating performance
Meeting market needs with a future-proof solution
The introduction of Syncros™ comes at a time when the industry is shifting toward greener chemistry solutions due to increasing regulatory pressures and growing consumer awareness. By providing a sustainable alternative to conventional hazardous crosslinkers, Stahl is leading the transition toward safer, future-proof solutions without compromising the high-performance standards expected in leather finishing applications.
With Syncros™ XR-55-400, customers can now achieve best-in-class leather finishes that enhance product durability while aligning with responsible production practices. Stahl remains committed to developing solutions that touch lives, for a better world.
