The invention concerns ionically and/or non-ionically hydrophilised, aqueous polyurethane-polyurea dispersions (PU dispersions) based on polycarbonate polyols and polytetramethylene glycol polyols, a process for their production and their use as coating compounds, in particular for the production of very stable thick foam deposits in a single coat.
L'invention concerne des dispersions aqueuses de polyuréthanne-polyurée, rendue hydrophiles par voie ionique et/ou non ionique, à base de polyols de polycarbonate et polyols de polytétraméthylèneglycol. L'invention concerne également un procédé pour la préparation des ces dispersions ainsi que leur utilisation comme agent d'enduction, notamment pour produire des couches de mousses épaisses, très stables, en une seule application.
