Abstract
Water-based polyurethane dispersion methodology relating to a chain-extended polyurethane, characterized in that the polyurethane dispersion includes 2, 5, 7, 10-tetraoxaundecane. The water-based polyurethane dispersion is suitable as a non-hazardous water-based coating composition for coatings with a particularly good adhesion on plastic or rubber substrates. The solvent 2, 5, 7, 10-tetraoxaundecane contained therein imparts good film coalescing, good adhesive properties and high strength of the polyurethane dispersion.
