The present invention relates to one-component moisture-curing compositions comprising at least one isocyanate-containing polyurethane polymer P which has a mean molecular weight of at least 4000 g/mol, and at least one polyaldimine ALD of the formula (I) or (II), where the content of isocyanate groups is at most 3.5% by weight, based on the sum of the isocyanate-containing constituents present in the composition. The compositions are suitable especially as sealants and are notable for good low-temperature performance.
La présente invention concerne une composition à composant unique durcissant à l'humidité comprenant au moins un polymère de polyuréthanne P comprenant des groupements isocyanate, ayant un poids moléculaire moyen supérieur ou égal à 4 000 g/mol, et au moins une polyaldimine ALD de formule (I) ou (II), la teneur en groupements isocyanate étant supérieure à 3,5 % en poids, par rapport à la somme des composants contenant des groupements isocyanate contenus dans la composition. Les compositions conviennent notamment en tant que matériaux d'étanchéité et se distinguent par un bon comportement à basse température.
