New C8 fluorocarbon technology
free oil repellent coating
Nano-Care Deutschland, a leading specialist in the production of ready-to-use high-tech coatings and their
precursors, has developed a new Nanoflex F-Bond coating system for water and oil repellency.
“Removal of C8 fluorocarbon technology, which will be banned due to its emissions of PFOS and PFOA,
leaves a significant performance gap in the market,” said Oliver Sonntag, Nano-Care Director. “The great
challenge for us has been to retain existing high standards of oil repellency – whilst eliminating long-chain Lenzing unveils sustainable complete shoe concept
