Stahl says it has launched a range of water-repellent solutions for leather products, including footwear, that are PFC-free and BTX-free. Called Neo, the new finish can be used on nappalan, suede, nubuck or full-grain leather. It can be combined with other Stahl products that comply with the guidelines of the Zero Discharge Hazardous Chemicals (ZDHC) list of restricted substances.
