BIONIC-FINISH®ECO will open up new perspectives to the clothing sector. With BIONIC-FINISH®ECO the company of Rudholm Group have succeeded in developing water repellant finishes that do NOT release flourorganic compounds. In the field of hydrophobic finishing, this is a specifically developed ecological alternative to marketable flourcarbon products.

Effective implementation of natural functions

Why do the feathers of birds not become wet? Why does this type of water repellency in nature work without perfluorinated compounds?

The RUDOLF GROUP has answered these questions by means of the scientific branch Bionic. Bionic does not mean to just imitate nature, but to realise its functional principles and to transfer them to technical solutions. Thus, novel, sustainable and ecologically advantageous technologies for imparting hydrophobic properties have been developed.

Hydrophobic finishing with BIONIC-FINISH® ECO is based on a fluorine-free recipe. Hyperbranched, hydrophobic polymers with ramified structures like in tree tops orientate in an orderly manner on the textile and crystallise on specifically adusted comb polymers. The optimum arrangement of many of these functional elements is highly effective. Additional boosters (crosslinking agents) ensure the optimum attachment and durability on many fibre substrates
