Fluorine-free into the future with Bionic


BIONIC-FINISH® ECO is the ecological alternative to previous durable hydrophobic finishes based on fluorocarbon resins. The nature of its chemical basis is more environmentally friendly than all durable water-repellent finishes before.

No perfluorinated compounds are used for manufacturing ®RUCO-DRY ECO, which is the finishing product of BIONIC-FINISH® ECO. Thus, ®RUCO-DRY ECO is not based on substances that contain perfluorinated groups.

In principle, ®RUCO-DRY ECO is biodegradable. However, according to the OECD test methods, the product cannot be called easily biodegradable but eliminable. As the polymeric components will remain and be effective beyond the life span of the textile finished with ®RUCO-DRY ECO, this is reasonable. Polyester fibres are not easily biodegradable either, but can be recycled without hesitation.

According to OECD tests, ®RUCO-DRY ECO can be easily eliminated from the effluent (> 80%) and is harmless regarding water toxicity (EC-50 (bacteria) > 100 mg/l, LC-50 (fish) > 100 mg/l) as well as oral toxicity (LD-50 (rat) > 5000 mg/kg).

BIONIC-FINISH®ECO is not resistant to dry cleaning or to solvents. Solvents dissolve the finishing film and penetrate it. This has to be considered in coating or laminating. Oil repellency can only be obtained by perfluorinated compounds.
