Polyurethane dispersions

®RUCO-COAT, ®RUCO-PUR, ®RUCO-BOND

Microdispersion - aqueous - NMP-free

 

RUCO-PUR / RUCO-COAT PU / RUCO-BOND
Tailor-made, NMP-free polyurethane dispersions and solutions

In the field of aqueous-based polyurethanes, the RUDOLF GROUP considers itself as a manufacturer and supplier of special niche products. The polyurethane dispersions und solutions comprise speciality products ranging from soft to hard, from anionic to cationic, from normal to highly resistant to hydrolysis, from soft to scratch-resistant, from hydrophobic to hydrophilic, from non-swelling to breathable ...

All our polyurethane dispersions are based on water and are NMP-free. The ionic character is paramount for many applications. Therefore, products of different ionic character have been developed. Special formulations and syntheses result in products with excellent film-forming properties which are, nevertheless, able to penetrate into the interior of the respective medium.
