There are different ways to make an upper water-repellent. The tanneries Sole Runner is working with do not use fluorocarbon and per fluorocarbon.
They do a water-repellent process in which they use Densodrin OF and Densodrin CD from Stahl chemicals which is silicon based and Perfectol HQ a paraffin based fat liquor to fix the water- repelling character.
Due to this process all our leathers will be free from Fluorocarbon and per fluorocarbon’s presence and will be a water repellent leather and not water proof.
There is no use of PFOS, PFAS, PFOA, PFCA, related compounds and chemicals that may degrade to PFCA.
