Fluorine-free water repellent textile finishing agents for ultimate performance

We all come from somewhere. We carry that place with us, wherever we go. We come from the scientific study of nature, its beauty, its logic, its mysteries. Somewhere within the unknown there’s purpose. And we are guided toward it.

Mother Nature designed many ways to benefit of water and to be sheltered from it. Many engineering challenges humans face can be solved by using natural design as a springboard. That’s bionics.

BIONIC-FINISH® ECO is Mother Nature’s work reproduced on textiles and apparel to protect us from water. To perform.

Function·The dendrimer technology

Contact us

From Mother Nature we borrowed the idea of dendrimers, molecules made of multi-functional branches that interact among themselves, co-crystallize, and self-organize into highly ordered, multi-component systems. They optimize the whole structure, attach to the textile and embed fluorine-free water repellent performance.

BIONIC-FINISH® ECO, based on proprietary dendrimer technology, comes as a family of unique non-halogenated, APEO-free, fluorine-free formulations suited for different materials and designed for different applications and needs.
