Highly effective water repellent agent for finishing fabrics of all fibre types.


BIONIC-FINISH® ECO is the umbrella brand for textiles that are finished with ®RUCO-DRY ECO and ®RUCO-DRY ECO PLUS and represents an ecological and pioneering technology for new, permanent water repellent finishing.

®RUCO-DRY ECO and ®RUCO-DRY ECO PLUS are based on fluorine-free formulas. Highly branched, hydrophobic polymers with dendritic structures are aligned across the textile and crystallise onto specially adjusted comb polymers. An optimal arrangement of many of these functional elements is highly effective. Additional boosters, e. g. ®RUCO-LINK RCX, which act as bonding agents, enable optimal adhesion and permanence on the fibre. BIONIC-FINISH® ECO combines ecology with pioneering, textile water repellent finishing. ®RUCO-DRY ECO PLUS was developed based on a technology which is environmentally friendly and fluorine-free using highly branched polymers, and already belongs to the 3rd generation of products based on fluorine-free formulas. It conveys higher efficiency combined with better permanence and sustainability. Oil and chemical repellency naturally cannot be achieved with this type of chemistry.

Practical implementation

Since 1995, H&M have been actively working to reduce the use and impact of hazardous chemicals. The RUDOLF GROUP has made every effort to eliminate these by products and has succeeded in developing PFOS and PFOA-free fluorocarbon water repellents with the so-called C6-generation. Despite these efforts, what is decisive for all parts of the textile chain, especially for brand manufacturers, is how public and consumers will in future react to this product optimisation. The entirely fluorocarbon-free BIONIC-FINISH®ECO will open up new perspectives to the clothing sector. With BIONIC-FINISH® ECO H&M have succeeded in developing water-repellent finishes that do NOT release fluoro-organic compounds. H&M purchase their goods from 700 suppliers of the textile industry, who are located in more than 20 countries in Europe, the Mediterranean region and Asia.

Possible replacement to

The sensible and sustainable withdrawal from fluorine chemistry demands the user to realistically assess the necessity for repellency of water and aqueous dirt. RUDOLF GROUP offers an innovative alternative to the as yet customary strong water repellency which is attained via fluorocarbon chemistry.
