MOISTURE-CURING POLYURETHANE COMPOSITION WITH GOOD LOW-TEMPERATURE PERFORMANCE

摘要

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.
