    摘要: The invention relates to the use of aqueous, isocyanate-free, polyurethane dispersions with a solid content of ≧30 wt. % and a solvent content of ≦10 wt. % in sports floor coverings. The inventive polyurethane dispersions are particularly suitable for use as bonding agents for elastic coatings, spray coatings or flow coatings on elastic or rigid undersurfaces, adhesion promoters or primary coatings, fillers for sealing pores, adhesives for gluing pre-fabricated plastic coatings or for sealing sports floor coverings. The inventive polyurethane dispersions are environmentally friendly and easy to manufacture. They are also partly characterized by improved product features, e.g. mechanical properties, UV resistance and color stability, with respect to the corresponding sports floor coverings.

    摘要: A solvent-free polyurethane-polymer hybrid dispersion having a high solids content of polymer or formulation constituents is described, which is obtainable by a) the multistage preparation of a polyurethane base dispersion and b) by the subsequent preparation of a polyurethane-polymer hybrid dispersion. This polyurethane-polymer hybrid dispersion not only is distinguished by complete freedom from solvents and high solids contents in combination with low viscosity and a technically simple preparation process but also has excellent mechanical properties and, owing to the low hydrophilicity, high water resistance. The polyurethane-polymer hybrid dispersion proposed according to the invention can be used in an outstanding manner in formulations for sport floor coverings, said dispersion being suitable in particular as a binder for resilient coats, as a spray or leveling coating on resilient or rigid substrates, as an adhesion promoter or primer, as filling compounds for sealing pores, as adhesive for the adhesive bonding of prefabricated resilient layers or for the sealing of sport floor coverings.
