Phambilini, izindwangu zangaphandle bezilashwa ngenhlanganisela ye-perfluorinated (PFCs) ukuze zixoshe amabala asuselwa kuwoyela, kodwa kutholakale ukuthi ziphila ngokuqhubekayo futhi ziyingozi lapho zichayeka kaningi.

Manje, inkampani yocwaningo yaseCanada isekele uhlobo lwangaphandle i-Arc'teryx ukuze kuthuthukiswe indwangu engenawoyela ye-fluorine exosha uwoyela kusetshenziswa indlela entsha ehlanganisa ukwakhiwa kwendwangu ne-PFC-free-based based coatings.
