Key takeaways:

• Next-gen DWRs: The growing diversity in PFAS-free options, such as UBC’s conifer-wax formulations and Lamoral’s multi-functional polymer coatings, signals a shift toward customisable, high-performance water repellents.
• Inspired by nature: By harnessing a compound called nonacosanol, UBC has created hydrophobic coatings that claim the repellency performance of traditional PFAS solutions, while being safer for health and the environment.
• Trade-offs in performance and sustainability: While showing promising hydrophobic properties, such coatings may require more frequent reapplication compared to legacy PFAS-based technologies, underlining the need for brands to reconsider durability expectations to support greener alternatives.
• Technology transfers offer new perspectives: Elsewhere, Lamoral’s patented polymer anchoring technology offers high-performing, biobased DWR coatings that meet textile industry standards for durability and water repellency, gaining recognition through partnerships like Speedo’s Olympic swimwear.

As the global outdoor industry has largely conceded the use of its most performant, durable water repellent solutions in respect of evident environmental concerns, the search for alternatives has intensified.

Both legacy ingredient providers and relative market newcomers are looking to seize the opportunity, with PFC- (perfluorinated) or indeed, PFAS-free (per- and polyfluoroalkyl substances) chemistries taking centre stage.
