Abstract: A composition including: at least one waterbased polyurethane dispersion containing ethylene oxide units; at least one cement; and at least one mineral filler. The composition can be mixed and applied without coagulation of the polyurethane dispersion. Upon curing, it has a high strength and good adhesion properties, with surprisingly low shrinkage and most surprisingly good water impermeability properties. It is particularly suitable for the use as repair mortar, waterproofing mortar or screed mortar.

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.
