| description | An aqueous polyurethane composition comprising a polyurethane which is the reaction product of: (A) an isocyanate-terminated prepolymer and (B) at least one active- hydrogen chain-extending compound comprising at least 0.20 stoichiometric equivalents with respect to the isocyanate content of the isocyanate-terminated prepolymer (A), of an active-hydrogen chain-extending compound selected from the group consisting of hydrazine, hydrazine derivatives and mixtures thereof; and wherein at least 0.2 stoichiometric equivalents of the anionic or potentially anionic water-dispersing groups are neutralised with ammonia.
L'invention concerne une composition aqueuse de polyuréthane comprenant un polyuréthane, produit de la réaction entre : (A) un prépolymère à extrémités isocyanate et (B) au moins un composé hydrogène actif extenseur de chaîne comprenant au moins 0,20 équivalents stoechiométriques des groupements isocyanates du prépolymère à extrémités isocyanate (A), d'un composé hydrogène actif extenseur de chaîne choisi parmi l'hydrazine, les dérivés d'hydrazine et les mélanges de ceux-ci ; et où au moins 0,2 équivalents stoechiométriques des groupements hydrodispersibles anioniques ou potentiellement anioniques sont neutralisés par l'ammoniac. |
