Intelligent self-organisation for
optimum water-repellent effects

Dendrimers can be produced step by step by combining multifunctional components. With each synthetic step of these hyperbranched polymers the number of reactive end groups grows exponentially. The specific control of reactions enables to functionalise end groups with hydrophobic residues at the end of a series of synthetic steps, which results in an extreme density of water-repellent groups. These hyperbranched, hydrophobic polymers are highly efficient and, due to their network structure, tend to self-organise and crystallise.

For optimum orientation and attaching to the fibre surface, ®RUCO-DRY ECO, the finishing product of BIONIC-FINISH®ECO, does not only use dendrimers but also specifically adjusted “comb“ polymers. The water-repellent effect level obtained in initial textile finishing has so far only been possible with fluorocarbon polymers.
